Drinking and driving

Alcohol and driving don’t mix. In a flashback to Alex’s drug influenced joyride in A Clockwork Orange, a Pune youth bumped into four people at different points on his late night drive through the city. When chased and caught he was found to be under the influence of alcohol.

In this post we take a look at the effects of alcohol on driving. We have already discussed some of the long term effects that necessitate imposing legal age limits for alcohol consumption in order to mitigate its neurotoxic effects on the developing brain.

30mg% is the legal blood alcohol concentration (BAC) limit for driving. Limits are a safety requirement to counter the adverse effects of alcohol on driving ability. The 30mg% level is often panned as being too low. Most countries have settled at a 50mg% threshold, some at 20mg%, others (considered very liberal) at 80mg%. Lets take a look at the effects on driving at these various blood alcohol concentrations (CDC 2011).

---

BAC	Effect on driving
20mg%	Visual deficits (problems with tracking of a moving object), Decline in multitasking ability (talking to a passenger while driving)
50mg%	Reduced coordination, difficulty steering, increased reaction time for braking by more than a second (Siliquini 2011)
80mg%	Problems with concentration, short term memory loss, reduced information processing capacity, impaired perception

---

How long after drinking alcohol is it safe to drive?
You need to wait at least as many hours as the ‘chota pegs’ (1oz or 30ml) you consumed. Alcohol is digested by the liver. The liver has a fixed capacity to metabolise about 8gms of alcohol in an hour. This is the amount of alcohol in 30ml of whisky, vodka, rum or gin. The equivalent dose is 250ml of beer or a glass (150ml) of wine. Each of these is considered as a ‘unit’ of alcohol.  However, consuming any quantity of alcohol within 6 hours prior to driving is associated with a doubling of the risk for a road traffic accident (Di Bartolomeo 2009). This effect of alcohol is present even at intake of 1-2 units which works out to a BAC of approximately 50mg%.

Blood alcohol levels as low as 20mg% impair driving ability under test conditions in a simulator. At 50mg% the impairments more than double the risk of an accident. The present 30mg% level may be legal but it remains impairing. Better to have a ‘designated driver’ - the person who does not drink for that particular evening. In case you want to we have already studied how to refuse alcohol.

DONT drink alcohol and drive

Hope for dementia caregivers - ARDSI Conference Pune 2011

Training for caregivers of persons with Alzheimer's disease helps address the distressing behaviours that arise in the affected person. Caregiver training also promotes wellness in caregivers by giving them the skills to  handle the relentless stress. Unfortunately most caregivers are unaware of the need or the availability of resources. The Alzheimer’s and Related Disorders Society of India (ARDSI) held its 16th conference in Nov 2011 at Pune. This significant event marked Pune’s arrival on the national dementia caregiver stage. Pune is now the 16th Indian city with an ARDSI chapter of its own. How does this help people with dementia (PwD) and their caregivers? The ARDSI Pune chapter “develops, coordinates and renders services in the field of dementia care, support, and training”.

The training aspect is particularly interesting. Conversations with caregivers at the clinic usually swing around to the day-to-day nitty-gritty of dealing with dementia, the impaired activities of daily living (ADLs) - keeping the person engaged, getting them to bathe, preventing them from wandering. Members of other fully functioning chapters whom I met at the conference animatedly discussed the caregiver training workshops and courses they held on a regular basis. These local courses are exactly what the doctor ordered - education for understanding and hands-on caregiver training.

The Dementia India Report 2010 was extensively quoted by many of the conference speakers. This document has dementia related statistics specifically for India and its states, and is an essential resource to leverage for obtain funds for dementia related activities. It also has details of services available for people with dementia - unfortunately data on support groups is as yet not available.

Caregiver training is a thrust area in dementia management. The 10/66 Dementia Research Group has developed a training package with a set of manuals, detailed instructions and a training video for caregivers and caregiver training. These are available for anyone to download after providing an email id. They provide a template that can be used by any individual or organisation involved in caring for persons with dementia.

The ARDSI conducts two geriatric care training courses; a six month certificate course and a one year post-graduate diploma course at its centre in Cochin. The number of persons with dementia in India is assessed to be 3.7 million in 2010. The ARDSI and similar courses will provide a pool of trained workers to care for the needs of people with dementia and their caregivers. This pool of personnel is not just on paper. The conference was over-booked. Extra seating had to be provided to accommodate the 100+ last minute attendees in the 400 seater main auditorium. Most of them were trainee social workers entering the field in time to meet the growing demand for their services.

Talk - not TV - for your toddler

Turn off the television and speak to your toddler. Talking is the best thing you could do today for your child’s psychological development. Talking is an interactive process in which your child exercises a core feature of being human - communicating through speech. Your child's vocabulary is directly proportional to the amount of time you spend talking.

Talking primes your child for independence. Speech evolves through attempts to communicate needs and feelings. Infants and toddlers are driven by evolution to master this complex process. You, the parent, play a key role in this two-way interaction. Infancy and toddler-hood are stages for developing secure bonding and attachment. The child is primed to bond with the mother or caregiver. The initial bond is secured by direct contact with the caregiver - through warmth, touch and voice. A secure attachment bond enables the infant seeks to explore the environment by attempts to crawl and later walk. The exploring toddler returns often to the parent to re-experience attachment security. It is here that talking plays a crucial role in maintaining the attachment bond at a distance. The child is then able to explore the environment away from direct contact with the parent.

Your one-year-old is psychologically unable to follow or learn from video. Some parents are convinced that certain TV channels are ‘educational’ for their toddler. The ability to comprehend video arises between 18 to 24 months of age (Pempek 2010). Prior to 2 years of age TV has little or no educational impact on the child, whatever the claims by media groups vying for their ‘eyeballs’. TV programming meant for 2-year-olds delays language and vocabulary development (AAP 2011, Zimmerman 2007).

Television is not a substitute for parenting. Parents leave the TV on to distract the child while they are engaged otherwise. Television holds the toddlers attention through its series of changing visual stimuli. This visual stimulus is powerful and distracting. While interacting with parents with the TV on in the background, the toddler is forced to shift attention to the TV once every 20 seconds. Even in adolescents, background TV adversely affects mental processing, memory and comprehension. Having the TV always on in the toddlers home interferes with unstructured play time that is critical to developing problem-solving skills and creativity. Repeated research has shown no developmental benefits for television exposure in infancy (Schmidt 2009, ).

Talk to and play with your children. Television is a medium that encourages passivity. TV delays vocabulary growth and language development in toddlers. Turn off the TV.

Diet and mental health

Mental health and diet quality are closely linked. The food choices you made as a teenager affect the development of conduct and emotional problems that continue into adulthood. Lifestyle diseases such as heart disease, diabetes and obesity are attributed to changes in diet and exercise habits. Recently there is increasing evidence that diet and exercise also have a major influence on mental health. Dieting peaks after the festival season. This post will help you avoid the 'isms' and fads and point you in the direction indicated by current research.

A good quality diet predicts better mental health

Evaluating the quality of the complete diet provides a better and more consistent picture of nutrition status than focusing on individual nutrients like magnesium or food groups like various fatty acids (omega, polyunsaturated). A traditional diet of vegetables, fruit, meat, fish, and whole grains is associated with lower risk for depression and for anxiety disorders as compared to a "western" diet of processed or fried foods, refined grains, sugary products, and beer (Jacka 2010).

Switching to a high quality diet improves mental health

Switching to a healthy diet improves mental health. Unhealthy diets are associated with lower scores on mental health tests. The best part is that improvements in diet quality are mirrored by improvements in mental health (Jacka 2011). Also the reverse, when diet quality deteriorates psychological functioning is adversely affected.

What constitutes a high quality diet?

The quality of diet is assessed using food frequency questionnaires. Points are allotted for each type and frequency of food consumed. For example one point is allotted for each of at least two fruit servings per day, at least four vegetable servings per day; using reduced fat or skimmed milk, using soy milk, consuming at least 500mL of milk per day; using high fibre, wholemeal, rye or multigrain breads; having at least four slices of bread per day; using polyunsaturated or monounsaturated spreads or no fat spread; having one or two eggs per week, using cottage cheese, using low fat cheese. Out of a maximum possible score of 74, the average is about 33.0 (+9.0).You can get some idea of your diet quality score from this chart (Collins 2008).

Preventive psychiatry

Improving diet quality improves mental health outcomes. Especially for adolescents this is an important preventive intervention. Three quarters of all long term psychiatric illness manifest during adolescence and early adulthood (Kessler 2005) . These illness are among the most disabling. They occur with a high enough frequency to contribute a major portion of life years lost due to disability. Mental health illnesses cause long-term problems at work and at home. They usually persist over the lifetime and require medication and support at various stages. Adopting a high quality diet is an important primary preventive intervention for improved mental health - easy to implement and proven to be effective.

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.
