Conduct Disorder and Behaviour Problems in Children



 

Conduct disorder and behaviour problems in children make the news when a 5-year old or a grandmother is killed while extorting money. Aggression in children  is just one of the offenses associated with conduct disorders . The seemingly lesser offenses of stealing in thousands from the home, or smoking 'weed' with their friends, pale in contrast. At the lowest end of the spectrum are those children who repeatedly confront authority in school or at home. Dubbed as 'monster kids' these children are viewed indulgently as being mischievous, naughty, 'bad', or 'delinquent'. Very seldom are they seen as having a mental health problem - a conduct disorder.

What is Conduct Disorder?

Behaviour problems that are persistent, violate the rights of others, go against societal norms, and disrupt family life, indicate a conduct disorder and merit psychiatric assessment. Conduct disorder is amongst the commonest childhood disorders seen in our clinic. Every one of us knows or has heard of a child with conduct disorders . Conduct disorder is characterised by the following behaviour problems .

Aggression

This child (maybe a 2 year old preschool cherub) picks fights, bullies, or physically hurts younger siblings at home. He is frequently taken to the principal's office for fighting in school. When this child enters the park the other children get ready to leave. He has often used a weapon (stick, cricket bat, stone or brick) to deliberately assault a person or hurt an animal.

Destruction of property

These children are wilfully destructive. They are the ones who scratch the paint off your new car, slash the seats of parked 2 wheelers, deface the lift, cut up a mothers dress, and tear the library book. More seriously they set fire to clothes and in extreme cases to vehicles.

Lying and deceit

These are children who steal from parents, grandparents, and classmates. They forge their parent's signature on school reports, cheques, and credit cards.They lie,  cheat and pilfer from shops.

Violation of rules

They stay out until late at night against home rules and curfews. They 'bunk' school to hang out with other antisocial friends, and run away from home overnight.

What happens to children with conduct disorder behaviours ?

Most parents feel a child will outgrow behaviour problems and conduct disorders .  However studies show this is not so. If not addressed and treated, children with conduct disorders are suspended from school, and have brushes with the law. Half of these children also have ADHD (Attention Deficit Hyperactivity Disorder) which further impacts their schooling. Broken relationships and marriages, and substance abuse including alcohol and cannabis abuse are common. As adults children with behaviour problems develop antisocial personalities and lead a criminal lifestyle. In the extreme a child with conduct disorder will murder his grandmother or a hapless neighbour's toddler.

Alzheimer's caregiver techniques

Caregivers living with persons having Alzheimer's Disease face specific problem behaviours. These behavioural problems result from memory loss that is the hallmark symptom of Alzheimer's. We have previously discussed resources giving hope for dementia caregivers. Caregiver do's and dont's for mental illnesses in general have also been highlighted. Living with Alzheimer's Disease is the theme for World Alzheimer's Day 2012. In this post we specify methods to help caregivers living with persons having Alzheimer's handle problems related to memory loss and reduce the burden of  care at home.

Caregiver techniques for Alzheimer's

1. Regular routine enables basic activities of daily living for a longer period of time. Make a visual time-table and regularly remind the person with Alzheimers to consult it so it becomes a habit.
2. Keep large clocks in each room and remind them of the time at every opportunity.
3. A personalised calendar with large figures helps plan and anticipate potentially confusing events such as a festival or travel.
4. A room with a window is great for orientation. Natural daylight and dark phases maintain the sleep-wake cycle.
5. Greet at every new meeting with date and time. The date is particularly difficult for a person with Alzheimer's to learn - it changes every day -  hence the disorientation. Repetition will keep the person with Alzheimers disease current with the month and year for longer.
6. Keep familiar objects like photos, phone, books, and decorative pieces in the same place. People with Alzheimer's often have to move from one set of caregivers to another. Placing these objects in the same general positions helps them to avoid confusion and  anxiety.
7. Photographs are important visual memory pegs. Two or three frames with photographs of the caregiver families and old friends reassures the person with Alzheimer's disease and facilitates their smooth transition between caregivers.
8. An identity card is essential for every person with  Alzheimer's. It must contain an address and an emergency contact number. It should be worn at all times, even inside the  house. Your loved one can wander out of an open door and not  be able to find her way back. Reinforce and rehearse showing or consulting the identity card on being asked for address or phone number.
9. Encourage and let them do the  things they can. Don't take over every activity or your caregiver burden will increase. Prompt them when they hesitate or take time. Help them in those activities they are unable to do.

Anti-dementia drugs delay nursing home admissions for upto a year. To make home this stay meaningful and to reduce the burden of care these methods need to be used by caregivers living with Alzheimer's Disease patients.

Alzheimers disease - mild cognitive impairment countdown

Alzheimers dementia is usually diagnosed when memory loss and behavioural symptoms are readily apparent to their caregivers. At this stage the primary concern is to slow further deterioration. Caregivers at the clinic have often wished they could have looked into the future. Many have a history of Alzheimers disease in their elderly and wondered whether there was an earlier way of knowing. New knowledge gives us hope in this direction.

Alzheimers disease before memory loss

We now have the beginnings of a time line in the countdown to dementia. It is now possible to trace the beginnings of Alzheimers Dementia up to 20 years before its manifestation with memory loss and impaired function.

20

Beta-amyloid levels in the cerebrospinal fluid (CSF)  begin to drop 20 years before the onset of dementia. Alzheimer's Disease is characterized by toxic deposition of specific beta-amyloid (Aβ1-42) plaques around the brain cells. In normal aging beta-amyloid continues to increase in the brain fluid. However, in Alzheimers Dementia brain fluid beta-amyloid is markedly reduced.This is due to reduce clearance of beta-amyloid from the brain to the blood and CSF, as well as increased beta-amyloid plaque deposition in the brain.

15

15 years before dementia onset, beta-amyloid deposits can be detected by amyloid imaging PET scans. The best known amyloid PET tracer is Pittsburgh Compound-B (PIB). PIB retention is found in over 90% clinically diagnosed AD patients.
Tau protein accumulation inside the brain cells (neurons) is the second hallmark of Alzheimer's disease.  Microtuble associated protein tau (MAPT) in the brain fluid (CSF) increases with age. In Alzheimer's disease tau levels are markedly increased and reflects damage to the neurons and axons (brain cells). High CSF tau level differentiates mild cognitive impairment (MCI) from that which progresses to Alzheimer's disease.
Shrinkage or atrophy of the brain becomes detectable by MRI. This atrophy is visible in brain structures that are essential for the conscious memory of facts and events. These areas are located in the brain’s medial temporal lobe. This shrinkage is apparent on using a visual rating system which also measures its severity. The more extensive the brain atrophy, the more advanced the clinical stage of Alzheimer’s disease.

10

PET Scan (FDG-PET) changes in the way the brain uses glucose are apparent 10 years before dementia. These PET scan changes correlate with progression of Alzheimers disease.
Episodic memory loss begins at this stage. Episodic memory loss is the inability to learn new information or to recall previously learned information. It manifests as forgetting of recent events and conversations, repetitive questions, repetitive retelling of stories, forgetting the date, forgetting appointments, misplacing objects, losing valuables, and forgetting that food is cooking on the stove. The formation of new episodic memories requires intact medial temporal lobes of the brain; these are progressively destroyed in Alzheimers disease.

5

Mild cognitive impairment (MCI) deveelops 5 years before dementia. People with mild cognitive impairment have problems with thinking and memory loss. Mild cognitive impairment does not interfere with everyday activities. Persons with mild cognitive impairment are often aware of their forgetfulness.
Preventive therapies for Alzheimers disease (AD) require the development of biomarkers that are sensitive to subtle brain changes occurring in the preclinical stage of the disease. Early diagnostics is necessary to identify and treat at risk individuals before irreversible neuronal loss occurs.

ADHD treatment improves academic performance

ADHD treatment improves academic performance

ADHD medication enhances academic performance when started early. ADHD drug treatment improves reading ability in children with Attention Deficit Hyperactivity Disorder (ADHD) and Dyslexia. New research shows that drug treatment of ADHD also improves maths ability especially when started early - at least by the 4th standard. Children starting treatment a year or two later show progressively greater declines in academic performance.

ADHD is characterised by inattention and hyperactive-impulsive behaviour. Parents who bring their children to the clinic are focused only on issues arising from the child's hyperactivity. Impairments due to inattention are not immediately apparent in the pre-school years. Depending on the severity of ADHD, inattention is unmasked when the child enters academic life in primary school or during the transitions to middle school, high school, and college. At each  of these stages an increasing demand is placed on the cognitive faculty of attention which the child's brain is not capable of meeting.

Children with ADHD fail to absorb formative academic concepts in primary school. However, rote learning or tutoring by the parents helps the child clear these initial stages. It is only later when the cognitive load exceeds the child's capacity to concentrate that academic problems become manifest. By this time the child's academic progress has already taken a downward trajectory. Reversing this trend and repairing the negative impact on the child's self-esteem entails considerably more effort, time and sustenance at these later stages. The earlier treatment for ADHD is initiated, the better.

Inattention in ADHD is due  to altered brain proteins. These are involved in modulation of the neurochemical - dopamine. This results in reduced dopamine in the synapse (fluid filled space that transmits information from one brain cell to another).  Altered dopamine modulation in the frontal lobe of the brain makes the child impulsive and distractible. ADHD medications act on dopamine and noradrenaline receptors to keep each dopamine molecule longer in the synaptic cleft. Dopamine is then available to stimulate the receptors for longer.

Parental concerns regarding side-effects of ADHD drug treatment on the developing child are largely unfounded. There is now evidence that shows long-term treatment with therapeutic doses of ADHD medication does not affect the developing brain or other standard measures of growth. ADHD drug treatment also does not increase the risk for addiction. As with any other medication side effects can arise at the start of treatment. Adherence to the review schedule will help monitor and mitigate these. All medication is prescribed after carefully weighing the risks and benefits. In the case of ADHD the risks are poor academic functioning and subsequent narrowing of career options at best, to dropping out or expulsion from school and subsequent delinquency at the worst. The benefits of treatment are highlighted in the  report card shown above.

Drug treatment of ADHD enhances academic performance and learning by reducing the inattention and hyperactivity of ADHD. The child with ADHD has attentional and impulse control issues. Inattention and hyperactivity interfere with classroom learning. The earlier ADHD treatment is started the better the outcome in terms of academic achievement. Many children have experienced these benefits.

Sexual Dysfunction and Relationships

The Erectile Dysfunction-Relationship Cycle

Erectile and sexual dysfunction in an ongoing relationship usually reflects difficulties between the partners. Relationship problems interfere with sexual feelings and cause or worsen erectile dysfunction.  Any experience that hinders the ability to be intimate, that leads to a feeling of inadequacy or distrust, or that develops a sense of being unloving or unlovable may result in erectile dysfunction.  Successive episodes of impotence are reinforcing. The man becomes increasingly anxious about his next sexual encounter. Erectile dysfunction is worsened by anticipatory anxiety about achieving and maintaining an erection interferes.  Sexual dysfunction interferes with pleasure in sexual contact and reduces ability to respond to sexual stimulation.

Erectile Dysfunction in the relationship cycle

In the early years of the relationship

• Lack of knowledge - there is a refractory period after sex before you can get the next orgasm. This refractory period increases gradually from a few minutes in teenagers to many days  in the elderly. Misguided enthusiasm after a period of separation causes a one-off problem with erection. This  is transient erectile problem is further reinforced by succeeding anxiety.
• Lack of privacy - the young couple moves into the parental home and has minimal access to privacy. Sex is a hurried activity with the focus on orgasm. Intimacy is not fostered. Subsequently there is dissatisfaction and a further build-up of anxiety.
• Stressors - careers with long working hours, night shift work and work from home leaves little time for the emotional intimacy that is requisite for sexual intimacy.

Middle phase

• Lifestyle changes - a sedentary  life style coupled with an indiscriminate diet result in obesity, a leading risk factor for erectile dysfunction. Excessive alcohol intake, and smoking have a direct impact on sexual functioning.
• Infidelity - is a major cause of anxiety and erectile dysfunction in the middle phase of the relationship. This  is especially so when the infidelity arises from insecurity - the man or woman attempting to prove continued youthfulness and desirability outside the relationship.

Later years

• Medical issues - chronic illnesses such as diabetes, and heart disease are commonly associated with erectile dysfunction.

What to do

• Don't panic - anxiety worsens erectile dysfunction. An occasional problem with  erection is not a reflection on your masculinity, and does not necessarily indicate a long term erectile dysfunction. Don't immediately try  to 'prove' yourself. Give it a days break to be safely out of the refractory period. There  will be  no trouble in the  next sexual encounter.
• Communicate - reassure your  partner of your continuing sexual interest in her. Communicate openly about  your condition. Involving your  partner improves the outcome of treatments for erectile dysfunction.
• Quit smoking
• Lose weight, exercise regularly
• Get treatment for alcohol or drug problems
• Work through relationship issues. Consider counseling if unable to work through  problems on your own.
• Depression, anxiety and stress related mental health issues should be addressed. Don't ignore them.

Whom to see for sexual dysfunction

• Consult a qualified psychiatrist. He or she  is the only person with the knowledge, training, and experience to deal with the psychological and medical issues that result in sexual dysfunction. The psychiatrist will also address issues in the relationship that are perpetuating the erectile dysfunction.
• Avoid self-styled sex therapists and sexologists
