Obesity in neurobiology

Progress in Neurobiology, 2008
Obesity reflects an imbalance between energy uptake and expenditure that is mediated by behavior. Obesity is a growing epidemic and a major risk factor for neurobiological diseases like stroke, dementia, intracranial hypertension and sleep disorders. Conversely, obesity can also be induced by neurobiological disorders and drugs. The etiology of obesity

Neurobiology of HIV

International Review of Psychiatry, 2008
The importance of HIV cognitive impairment, including HIV associated dementia (HAD) and minor cognitive/motor disorder, has continued in the era of highly active antiretroviral therapy (HAART). Despite the relative efficacy of HAART in controlling HIV disease, there is no treatment which specifically targets the cause of HAD nor promotes neuronal ...

The Neurobiology of Psychopathy

Psychiatric Clinics of North America, 2008
Numerous studies have tackled the complex challenge of understanding the neural substrates of psychopathy, revealing that brain abnormalities exist on several levels and in several structures. As we discover more about complex neural networks, it becomes increasingly difficult to clarify how these systems interact with each other to produce the ...

The neurobiology of suicide

The Lancet Psychiatry, 2014
The stress-diathesis model posits that suicide is the result of an interaction between state-dependent (environmental) stressors and a trait-like diathesis or susceptibility to suicidal behaviour, independent of psychiatric disorders. Findings from post-mortem studies of the brain and from genomic and in-vivo neuroimaging studies indicate a biological ...
