Pathological Shyness as a Pathway to Alcoholism

by William Yates, M.D. in Brain Posts

Alcohol abuse and dependence risk is influenced by a variety of mental disorders. Probably the strongest association is between antisocial personality, alcohol and drug abuse. But anxiety and mood disorders also commonly influence the risk of developing a substance abuse problem.A recent study examined the association between alcohol use disorder and social anxiety disorder.

Genetics of Methamphetamine Psychosis

by William Yates, M.D. in Brain Posts

I have been working on updating a lecture on substance-induced psychosis. In the last few years a significant amount of research has been published on methamphetamine psychosis. Methamphetamine can produce a psychotic state characterized by paranoia, agitation and behavioral problems. Not all individuals appear to experience this induced state. This leads to the question of what factors might be related to the risk of psychosis in those using methamphetamine. Certain dose and duration of met........ Read more »

Eating Chocolate and Depression

by William Yates, M.D. in Brain Posts

A recent study examined the correlation between chocolate consumption and self-reported depression symptoms. This study used a cross-sectional design and a self-report measure of nutritional intake--the Fred Hutchinson Food Frequency Questionnaire.Depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression Scale (CES-D). Subjects were stratified into three groups: CES-D score of 16 or less (non-depressed), CES-D score of 16-22 (positive depression screen) and CES-D ........ Read more »

When Is It Time to Stop Driving in Dementia?

by William Yates, M.D. in Brain Posts

A common clinical problem in aging is when should driving a motor vehicle be discontinued. When does driving become a significant safety hazard as cognition and motor skills decline?The American Academy of Neurology recently published a Practice Parameter update: Evaluation and management of driving risk in dementia. This important review provides clinicians and family members with assistance in making an accurate and timely decision.The authors of the guideline review research evidence of a v........

Set-shifting as a Biomarker for Eating Disorders

by William Yates, M.D. in Brain Posts

Significant research focuses on the identification of biomarkers in a a variety of psychiatric disorders. A biomarker can be any biological variable that is associated with an illness. Biomarkers are important because they provide an opportunity to identify high-risk individuals prior to disease onset. Early intervention in these individuals may reduce the risk of illness or reduce the severity and impairment of the disorder. Biomarkers may also be valuable in identifying genes associated wi........ Read more »

Aspirin Endorsed as Effective Agent in Migraine

by William Yates, M.D. in Brain Posts

Migraine headaches are a common type of severe headache that can cause significant episodic disability. The one-year prevalence for migraine is estimated to be 18% for women and 6% for men in the U.S. Headaches typically last from four to 72 hours and can interfere with work and interpersonal function.A recent Cochrane Review examined the effectiveness of aspirin. The review included a comparison between aspirin and more recently developed triptan drugs such as sumatriptin (Imitrex). Thirtee........ Read more »

Diagnostic Challenges in Pediatric Bipolar Disorder

by William Yates, M.D. in Brain Posts

This is the third in a series of posts from the NARSAD-sponsored Healthy Minds Across America 2010 symposium in Tulsa, Oklahoma. The first two posts covered deep brain stimulation in depression and the neurocircuitry of depression. Dr. Robert Kowatch presented a review of the key issues in pediatric mood disorder. Dr. Kowatch is a child and adolescent psychiatrist from the University of Cincinnati who has been involved in assessment of bipolar disorder and depression. A portion of his presen........

Brain Neurocircuitry in Depression

by William Yates, M.D. in Brain Posts

This is the second in a series of three posts from my notes at the NARSAD Healthy Minds Across American 2010 symposium in Tulsa, Oklahoma. The University of Oklahoma-Tulsa and OU-Tulsa President Dr. Gerry Clancy served as host for the event. Following a presentation by Dr. Helen Mayberg from Emory University (notes here), Dr. Wayne Drevets presented a review of neurocircuitry in depression.Dr. Drevets has been a leader in neuroimaging research in mood disorders. His studies have included usin........ Read more »

Omega-3 Fatty Acids and Brain Cortex Activity

by William Yates, M.D. in Brain Posts

There is some research evidence to support the cognitive benefits of omega 3 fatty acids. These natural compounds are found in a variety of dietary sources including tuna, salmon and sardines. McNamara et al and colleagues at the University of Cincinnati recently published an interesting brain fMRI study of DHA (docosahexaenoic acid) supplementation. DHA is a key component of omega-3 fatty acids. Here are the key elements of the design:33 healthily boys age 8 to 10 years were randomizedSubjec........ Read more »
