When you hear hoofbeats, think horses and zebras: The importance of a wide differential when it comes to frontotemporal lobar degeneration.

Frontotemporal lobar degeneration (Frontotemporal dementia in DSM 4/FTD) is a progressive brain disease which frequently presents with neuropsychiatric symptoms. Prevalence of FTD is low, however the prognosis is poor. Early identification of FTD may improve quality of life, minimize behavioral disturbances and help with end of life planning. Diagnosis of FTD is often a diagnostic challenge as it has wide differentials. Authors discuss three clinical cases with their initial clinical presentation, diagnostic complexity and subsequent management.

Conversion Disorder- Mind versus Body: A Review.

In this article, the authors accentuate the signs and symptoms of conversion disorder and the significance of clinical judgment and expertise in order to reach the right diagnosis. The authors review the literature and provide information on the etiology, prevalence, diagnostic criteria, and the treatment methods currently employed in the management of conversion disorder. Of note, the advancements of neuropsychology and brain imaging have led to emergence of a relatively sophisticated picture of the neuroscientific psychopathology of complex mental illnesses, including conversion disorder. The available evidence suggests new methods with which to test hypotheses about the neural circuits underlying conversion symptoms. In context of this, the authors also explore the neurobiological understanding of conversion disorder.

Frendak to phenis to breivik: an examination of the imposed insanity defense.

The imposition of the insanity defense is a complicated psycho-legal scenario. Globally, definitions of insanity differ from country to country. In a multitude of cases, a determination of insanity at the time of a criminal act means the offender will not be considered responsible for his or her action(s). In many jurisdictions, concerns have been raised that the insanity defense has been used to mitigate punishment, usually after a particularly heinous crime. In this review, the authors use three cases - Frendak, Phenis, and Breivik to demonstrate how the imposition of the insanity defense has been used for legal purposes in the past and present. In an effort to give more background to each of the above-mentioned cases, the writers have provided some details to aid comprehension. The authors offer recommendations for the ethical forensic evaluator unburdened by partisan allegiance and invested in the search for truth. This review article relies on peer-reviewed articles available from PubMed, Meharry Online Library, and legal dictionaries. We also cross-referenced reputable news sources to ensure the validity of the facts we present.

Alcohol: the lubricant to suicidality.

Suicide is a major public health problem in the United States as well as around the world. The significant role that alcohol plays in suicidality is well known and accepted in the scientific community. The use of alcohol does not necessarily lead to suicide, but through its action and effects, alcohol is an important proximal risk factor for suicidal behavior. There is very little data showing how and why alcohol exerts such tremendous influence and "lubricates the gears" to propel the act of committing suicide. This article will elucidate the complex relationship between alcohol and suicide and how alcohol use can lead to suicide. The article also describes how alcohol affects brain neurophysiology in regards to suicidal behavior.
