Tattoos - true love will never fade

What is the motivation or psychology behind obtaining a tattoo? Tattooing as a form of decorative body art has moved out of the realm of cults and organisations into mainstream society. It is increasingly common to see patients sporting a new tattoo. "Just like that, doctor. My friends were getting one". The Pune magazines reflect this new found art form through full page articles every other week. Driving through the some parts of Pune takes you past at least three studios specialising in the art of tattooing.

Here we are concerned with the psychological aspects of tattooing. As compared to body-piercing, a tattoo is relatively permanent and more deliberate operation. For the moment set aside doubts over hygiene, HIV, and hepatitis.

10 reasons people get a tattoo

  1. Beauty, art, and fashion. Tattoos are a means of decorating the body with a permanent fashion accessory. Many tattooed individuals refer to their tattoos as a piece of art. 
  2. Individuality. A tattoo fulfils the desire to create a distinct self-identity. The symbols or words embellishing the skin creates a special message that distinguishes the person from others. The individual gains a sense of control over their appearance and identity. We see this especially in teenagers brought in by their parents.
  3. Personal narrative. Women recovering from abuse create a new understanding of the injured part of the body. They reclaim possession through the deliberate and painful procedure of body modification. Tattoos have a self-healing effect in this reclamation of the body. 
  4. Physical endurance. For some tattoos are a statement about testing their threshold for pain endurance.  
  5. Group affiliations and commitment. Body ornaments are a permanent sign of love and commitment. The wish to belong to a certain community or to show affiliation to a particular group is a common reason for getting a tattoo. 
  6. Resistance. Tattoos are a provocative protest against parents and society, especially in college students. Body modification has long been associated with subcultural movements and criminal tendencies. Until recently most studies on tattooing were done on prison populations.
  7. Spirituality and cultural tradition. Body modifications emphasise personal affiliation to cultures and their spirituality. Esoteric symbols that convey special meaning are tattooed as a permanent reminder.
  8. Addiction. Tattoos and piercings possess an addictive character through the release of endorphins. These substances are released in brain areas in association with painful penetration of the body.
  9. Sexual motivation. Tattooing is a form of expressing sexual affectations and of emphasising ones own sexuality. 
  10. No specific reason. A tattoo may be obtained impulsively on the spur of the moment. Some individuals may be under the influence of alcohol or drugs while acquiring their piece of body art.

Reasons people have a tattoo removed

People are mostly satisfied with the actual design of their tattoo.

Most want their tattoo removed for personal reasons. This occurs when the quest for uniqueness turns into stigma, negative comments, and clothes problems. Poor decision making and subsequent personal regret seem to be frequent motivations for tattoo removal.

An improved sense of self and maturity is another factor. Especially for those who obtained their tattoos for internal expectations of self-identity at an early age. Many are still trying to dissociate from the past and improve self-identity. More than 40% of persons who choose a tattoo to feel unique are disillusioned when their unique product loses its luster and excitement.

Professional/social reasons account for another third of those motivated for tattoo removal. A new job or career is a major motivation. Negative workplace attitudes toward tattoos and perceived interference for a tattooed individual’s achievement is common. There is a perception of lowered credibility, competence, and sociability that diminishes the image of tattoo wearer in the workplace.

The possession risks are more for women than for men. More than two thirds of those seeking tattoo removal are women. Society support for women with tattoos is not as strong as for men. Strong tattoo support from significant others and friends is counterbalanced by negative remarks about the tattoos from fathers, physicians, and the public. Negative responses are also documented among career-oriented women with tattoos. Women still need to deliberately think about controlling the body placement of their tattoos to avoid the possession risks and to increase their own psychological comfort.

Learning Disability - academic underachievement

learning disorder
Impaired spelling and arithmetic in Standard 3 boy with Learning Disorder

Learning Disorder (LD) is characterised by impaired acquisition of academic skills. This impairment in scholastic skills is not due to intellectual disability, physical disorders, emotional disturbances, or environmental, cultural, or economic disadvantage.

There is a gap between ability and application. The child may know what is asked, is able to explain it verbally, but is unable to put it down in writing. Learning Disorder could affect any of the three scholastic Rs – Reading, wRiting or aRithmetic.

Types of Learning Disability

  1. Dyslexia – is the commonest learning disability (80%). It is marked by impairment of the ability to recognize and understand written words.
  2. Dyscalculia – problems with doing math, understanding time, using money.
  3. Dysgraphia – problems with handwriting, spelling.
  4. Dyspraxia – problems with hand-eye coordination and balance, difficulties with fine motor skills.

Signs and Symptoms

Most children with a Learning Disability are not diagnosed until they are in Standard 2-3 or 7-8 years of age. Remarks like ‘can do better’ or ‘handwriting needs to improve’ are often the first warning signs to appear in the report card. Many of these children would have been the stars of their nursery or kindergarten class. The transition to assessment of written output in primary school is what unmasks the disorder. The aware teacher is able to help the parents understand and put the parents on the path to remedial teaching.

Parents should watch out for

  • Reading may be slow or there is repeated rereading or skipping of an entire section. In the lower classes the child learns to memorise and reproduce entire chapters. Later the child is unable to hold the increasing amounts of material in memory, grades plummet, and confused parents are left searching for answers.
  • Problems in copying from the blackboard or a book. This is a frequent complaint of the teacher. Classwork is left incomplete. The child tries to copy from their partner and is punished for distracting the class.
  • Poor handwriting or drawing – their exercise books are messy, with frequent scratching out and erasing. This is especially so when the child writes on blank paper. It is also a reason why the child performs poorly in exams – they just cannot write quickly enough. They run out of time before they reach the last few questions.
  • Other signs in more severe conditions
    • Reversing numbers and letters while reading or writing - For example, confusing ‘b’ and ‘d’
    • Mixing the order of letters or numbers. Writing ‘twon’ instead of ‘town’.
    • Skipping letters in spelling. The child says ‘grass’ but writes ‘gas’.
    • Forgetting words they know well.
    • Weakness in mathematics.

Conquering Learning Disorder

  • Approach a centre undertaking diagnosis of learning disabilities.
  • A complete history of the child’s birth, milestones, health and academic record
  • Physical exam to exclude problems related to vision and hearing
  • Psychometry - to demonstrate specific academic problems that are not associated intellectual disability
  • Psychiatric assessment - to address associated anxiety, phobias and depression that arise out of repeated academic failures.
  • Psychiatric assessment - to exclude or address Attention Deficit Hyperactivity Disorder (ADHD) a common comorbidity. 15-40% of children with ADHD also have dyslexia.
  • Remedial teaching is essential to overcome learning problems 

Drug treatment for dyslexia?

There is a growing body of research to show that at least in children who have both ADHD and dyslexia there are significant improvements in reading ability with ADHD medication. These improvements in reading ability are not related merely to improvements in attention. The brain systems responsible for therapeutic improvement in children with ADHD + dyslexia are probably different from those in children with ADHD alone. The finding that selective areas of working memory can be enhanced by these medications is important, as poor working memory function appears to be a mental constraint on academic learning.

Stress in the festival season

festival time
Festivals as a source of stress? Festivals are meant to be a time of happiness, enjoyment and family togetherness. However for some it can be time of great stress and can adversely affect mental health. The extended festival season starts around Independence Day (15th Aug) and extends right up to New Year including Ganesh Chathurti, Dusshera, and Diwali. Vacations have a positive effect on well-being. However, these effects fade soon after resumption of work (de Bloom 2009). These four months of celebration are associated with psychological distress and mental health problems for many individuals and their families.

Festival distress

(Harion 2009)
Expectations take their toll on the family. Festivals are a prime time for couples to come in for counselling with relationship problems, problems with in-laws, siblings and their children. 'Don't we get to celebrate at least once in our own home?". They end up celebrating each in their own parental homes at Pune and Ahmedabad.

For those in the workforce it means negotiating and competing with everyone else for leave or being the only one left in the office. No one at home understands why you cannot get leave. No one understands why work-pressures and deadlines increase in the time leading up to the holiday. Financial stress also comes into the picture; cool electronics, gifts, partying and vacation trips cost.

For people with mental health problems festivals are another source of stress. Well intentioned, though ill informed relatives prevail on them to stop their medications 'they are addicting', 'why do you need to take them if you're allright?' Many are coaxed into stopping medications entirely.They relapse some time after they return to work, when the social supports are at a minimum and the beneficial effects of the vacation begin to wear off. That is also the time when they have to start paying out the EMIs. This time lag to relapse after stopping psychotropic medication is a prominent factor in non-adherence. 'But he was allright at home. It's the job that is causing stress; we are thinking of relocating'.

Fasting and sleep deprivation are associated in the run up to the festivities. In vulnerable people, especially those with mental health problems, these can play havoc with the body rhythm and with medication regimens leading to a relapse. Every religion excuses ill followers the rigours of these rituals, yet the very people who should be supporting moderation often goad their vulnerable members to comply. 'I thought he was just being lazy'.

Alcoholism is another problem that is likely to recur. It starts insidiously at the beginning of the festival season. By the time the season ends its time for another stint of 'deaddiction'. Binge drinking at parties is just another problem that requires to be addressed recurrently.

Violence and injuries in the home occur through the combination of excitement, stress, tiredness and alcohol. Pressures lead to conflict and then violence. Domestic abuse is about one-third more likely on the day of the festival than the daily average. Homicide rates are generally higher on all major holidays.

Loneliness and isolation are particular issues at festivals. The holiday season is the time of the year when our desire for social contact is most likely to outstrip what our circumstances will allow; it is into this gap that loneliness creeps (Lancet 2010). As festivals are associated with friends and family, it can be difficult for those on their own to avoid feeling lonely at this time. This is especially so for older people living alone who may have no one to spend the festive season with. The loneliness felt on the festival day is often the worst. Festivals can be a sad and nostalgic time, when the loss of a family member may become especially painful. It is often a difficult time for bereaved people. The rates of suicide are known to increase especially on New Years Day (Bridges 2004).

What to do?

Prior to the festival
  1. Communicate. Make your festival plans keeping your spouse in mind. If there were problems  last year don't expect them to disappear. ' I thought we agreed on that last year'. Putting off the discussion could ruin your festivities.
  2. Collaborate. Work together to find a solution that satisfies the needs of all parties. You may not get everything you want, but you get enough of what you want to feel satisfied. Colaboration requires respect for the needs of the other party, communication skills, patience, and creativity. Parties usually do better when they collaborate than when they compete.
  3. Watch the finances. Budget for the expenses and keep a track.
During the festival
  1. Limit your alcohol. Don't drink if you don't want to.
  2. Keep to your normal sleep-wake schedule as far as practicable. When it is disrupted return to your normal schedule at the earliest. Take some time out for exercise.
  3. Take some time off for just yourself and your family. A walk, movie or meal away from the others will contribute to a few more days of harmony.
  4. Your medication is sacrosanct. Don't negotiate on this.
Strategies for loneliness
(Masi 2010)
  1. Improve social skills: After relying on a partner to share experiences and thoughts a separation, breakup or bereavement requires relearning of skills needed to build new relationships and participate in community functions.
  2. Enhance social support: Find a listening ear – people who are lonely can find it helpful to speak to a counsellor or someone removed from their situation.
  3. Increase opportunities for social contact: Be a volunteer – many charities and organisations need help at festivals and you could spend a few hours working as a volunteer. The absence of close family need not be the end of companionship. 
  4. Address maladaptive social cognition: Loneliness can also be tackled by helping people to feel happier in their own company.
    • 'Everyone else is having a good time'. Keep busy – try to stop the festival taking over your life. Make time for enjoyable activities, such as reading, walks, joining a social club or going for a movie.
    • 'What's the point, I'm just not up to it'. Take some physical exercise – this reduces stress and enhances mood. Just getting off the sofa and getting outside should improve mood.
  5. Visit an older neighbour who lives alone if you have a little spare time on your hands over the holidays; it might be just what they need to make their holiday a happy one.

Diagnosing Alzheimer's Dementia

Alzheimer's Disease amyloid plaques and neuro-fibrillay tangles in brain tissue
Microscopic picture of the brain showing amyloid plaques and
 neurofibrillary tangles first seen by Alois Alzheimer in 1907

The diagnosis of Alzheimer's disease became headline news when the defence counsel of a prominent citizen of  Pune stated they were awaiting results of his brain MRI to finalise the diagnosis of dementia. Recently a patient's medication was stopped when his neuro-physician declared there were 'no plaques on MRI so it is not a case of Alzheimers'. The caregivers returned to me when his behaviour problems recurred.

Dementia including that of the Alzheimer's type is a clinical diagnosis (Grand 2011). Dementia is characterised by a triad of
  1. Progressive deterioration of mental processes (cognitive abilities)
  2. Behavioural and psychological symptoms of dementia (BPSD)
  3. Difficulties carrying out day-to-day activities (activities of daily living or ADL).  
Alzheimer's Disease is commonest dementia after 65 years of age Alzheimer's dementia has an insidious onset, and progresses gradually and inexorably. This natural course is a key differentiator Alzheimer's from other forms of dementia. Dementia is suspected when a caregiver of an elderly person, or sometimes a person with a family history of dementia, becomes concerned about problems with memory. The diagnosis is purely clinical. No laboratory test or imaging (including MRI) is required to diagnose Alzheimer's disease. These investigations can only help differentiate the other forms of dementia when those are suspected.

Memory problems are a core feature of the disease. These manifest as
  • Difficulty recalling details of recent events (forgets he has already dropped his grandchild to school), personal conversations, or specific elements of a task she is performing (eg, preparing a meal)
  • Asking the same question multiple times while denying repeated questioning
  • Tendency to make up events to fill memory gaps and to give inaccurate responses to questions (what he had for breakfast)
Other common cognitive concerns that could indicate dementia of the Alzheimer or any other type
  • Disoreintation to time and place. As the illness progresses orientation worsens to include problems identifying familiar places, family members, or other well known people.
  • Difficulties with activities of daily living (ADL). Problems with dressing or using common utensils
  • Language impairments resulting in decreased conversational output, word-finding difficulties, and limited vocabulary.
  • Visuo-spatial dysfunction manifest as impaired driving ability, and getting lost
  • Problems with mathematical calculations impair ability to use money and balance finances.
  • Impaired judgement in novel situations (difficulty planning a vacation).
Behavioural and psychological symptoms (BPSD)
  • Depression occurs in up to 50% of individuals with Alzheimer's Dementia, and may be attributed to awareness of cognitive changes
  • Lack of feeling or emotion (apathy) is associated with significant caregiver distress
  • Psychosis generally occurs later in the disease course. Delusions are predominantly paranoid in nature, with fears of personal harm or mistreatment, theft of personal property (usually related to financial matters), and marital infidelity. Hallucinations are less common than delusions, and tend to be visual.
  • Other behavioural symptoms include agitation, wandering, and sleep disturbances.

Diagnosis of Alzheimer's Disease is based on 
  1. Detailed history to identify memory deficits, and other cognitive symptoms and assess their impact on the individual and family.
  2. A thorough clinical exam (mental status examination) confirms the impairments in memory and cognition, and delineates the behavioural and psychiatric symptoms that cause caregivers concern. This usually includes using validated and standardised screening pencil and paper tests. 
  3. Psychological testing confirms and quantifies the impairments across various areas of brain function (memory, language, visuo-spatial), assesses the treatment response, and documents progression of the illness with time.

Laboratory tests including MRI only differentiate Alzheimer's disease from other disorders such as subdural haematoma, brain tumour, hydrocephalus, and dementia associated with vascular disease. Magnetic Resonance Imaging (MRI) has no other clinical utility in Alzheimer's disease. These tests are not required or mandated by any classification system including that of the WHO (ICD) or the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer’s Disease and Related Disorders Association (NINCDS-ADRDA).

Amyloid plaques, and neurofibrillary tangles are the hallmark of Alzheimer's disease and are required for a definitive diagnosis. These were first discovered by Alois Alzheimer in 1907.  His slides were rediscovered in 1992 and 1997. The rediscovered images show the classical pathological signs of the disease named after him. Amyloid plaques and neurofibrillary tangles are seen on microscopic examination of brain tissue using special staining techniques or by electron microscopy. Therefore the only way to obtain a definitive diagnosis of Alzheimer's disease is to obtain a brain tissue sample by biopsy or on autopsy. No MRI, however advanced can detect plaques.
For the purpose of treatment a probable diagnosis using bedside techniques of history and clinical examination is all that is required to diagnose Alzheimer's disease.

Parental supervision of children and adolescents

parental supervision and injuries in children with high intensity behaviour
Parental supervision protects boisterous children from injury:
More time unsupervised corresponds to more injury 
“To my parents we were just two girls in the bedroom”. What exactly was going on? Without adequate supervision the parents of this teenager never found out; the memories returned to haunt her in adulthood. Studies comparing children with and without parental supervision show that lax parental supervision is associated with injury in toddlers and preschoolers; conduct problems in school going children; and road accidents, addictions, gambling and sexual risk taking in teenagers.

Parental supervision has three dimensions (Gitanjali 2004)
  1. Attention - watching or listening 
  2. Proximity - within or beyond reach 
  3. Continuity - constant, intermittent, or not at all 

Two factors determine the degree to which a child would be left unsupervised (Morrongiello 2008)
  1. Parent’s conscientiousness - the more conscientious the parent more the supervision
  2. Child’s propensity for risky behaviour - the more impulsive and sensation seeking the child the more likely the child will be kept in direct view. 

Distinguishing adequate from neglectful supervision is not straight forward. The consequences of lower levels of supervision are not uniform for all children. The consequences depend to a great extent on child attributes. For children with high sensation seeking, even close supervision is not adequate to prevent injury. For children who are high in behavioural control, even not supervising does not elevate risk of injury.

Whether or not children comply with their parents’ requests to behave in safe ways is a complex interaction of parenting style, attachment style,  and child temperament. The level of supervision necessary to ensure a child’s safety should finally be based on the child’s characteristics. The only reliable maxim is that the time children could be safely left unsupervised generally increases with child age.

Parental supervision of an adolescent differs from supervising a younger child (DeVore 2005). Direct parental observation gradually gives way to indirect parental ‘‘monitoring’. This indirect supervision involves ongoing communication between parents and adolescents about the adolescents’
  • Whereabouts
  • Friends they are with
  • Schedule to return home
  • Contact information enabling parents to directly communicate with adolescents. 
Effective supervision entails active participation of the adolescent, and honest communication between adolescent and parents.

Parental monitoring buffers negative peer influence. Strong peer attachments and increasing independence from the family is a normal part of adolescent development. Unfortunately, youth whose peers engage in high-risk behaviour are at high risk for the development of similar behaviours. Not only are high levels of monitoring protective, low levels of parental monitoring have been associated with numerous risk behaviours.

More unsupervised time is associated with more sexual activity in youth (Cohen 2002). In one urban study more than half of sexually active youth had sex at home after school. For boys, sex and drug-related risks increase with amount of unsupervised time. Trust and communication did not predict decreases in problem behaviour as strongly as did monitoring. Parental monitoring may be particularly protective for high-risk young urban adolescents; those who spend a significant amount of non-school time unsupervised.
