When Will We Solve Mental Illness? The second guidepost concerns the impact of biology.
Although there are several important exceptions, measurable differences in brain biology appear to contribute only a fraction of added risk for developing persistent mental problems. Genetic inheritance surely plays a role, but it falls well short of a stand-alone “cause” in most people who receive a diagnosis. The remainder of the risk is supplied by experience: the messy combination of trauma, substance use, loss and identity crises that make up an individual’s intimate, personal history.
Biology has nothing to say about those factors, but people do. Millions of individuals who develop a disabling mental illness either recover entirely or learn to manage their distress in ways that give them back a full life. Many participants are veterans of the psychiatric system, people who have received multiple diagnoses and decided to leave medical care behind. All Disorders.

People suffering from a debilitating and often discounted disease known as chronic fatigue syndrome may soon have something they’ve been seeking for decades: scientific proof of their ailment.
Researchers at the Stanford University School of Medicine have created a blood test that can flag the disease, which currently lacks a standard, reliable diagnostic test. “Too often, this disease is categorized as imaginary,” said Ron Davis, PhD, professor of biochemistry and of genetics. When individuals with chronic fatigue syndrome seek help from a doctor, they may undergo a series of tests that check liver, kidney and heart function, as well as blood and immune cell counts, Davis said. “All these different tests would normally guide the doctor toward one illness or another, but for chronic fatigue syndrome patients, the results all come back normal,” he said. The problem, he said, is that they’re not looking deep enough.

Huntington's Disease. The Surprising Solution to the Imposter Syndrome. Korsakoff's Syndrome: A Critical Review - PubMed. In this review, we present a survey on Korsakoff's syndrome (KS), a residual syndrome in patients who suffered from a Wernicke encephalopathy (WE) that is predominantly characterized by global amnesia, and in more severe cases also by cognitive and behavioral dysfunction.
We describe the history of KS and its definition, its epidemiology, and the lack of consensus criteria for its diagnosis. The cognitive and behavioral symptoms of KS, which include anterograde and retrograde amnesia, executive dysfunction, confabulation, apathy, as well as affective and social-cognitive impairments, are discussed. Moreover, recent insights into the underlying neurocognitive mechanisms of these symptoms are presented. In addition, the evidence so far on the etiology of KS is examined, highlighting the role of thiamine and alcohol and discussing the continuity hypothesis.

Spider venom key to pain relief without side-effects. Molecules in tarantula venom could be used as an alternative to opioid pain killers for people seeking chronic pain relief.
University of Queensland researchers have designed a novel tarantula venom mini-protein that can potentially relieve severe pain without addiction. Dr Christina Schroeder from UQ's Institute for Molecular Bioscience said the current opioid crisis around the world meant urgent alternatives to morphine and morphine-like drugs, such as fentanyl and oxycodone, were desperately needed. International Journal of Neural Systems. Reel-Example: Conduction Aphasia 1. Obesity is Inflammatory Disease, Rat Study Shows. Scientists led by Dr David Fairlie from the University of Queensland, Australia, have found abnormal amounts of an inflammatory protein called PAR2 in the fat tissues of overweight and obese rats and humans.
PAR2 is also increased on the surfaces of human immune cells by common fatty acids in the diet. When obese rats on a diet high in sugar and fat were given a new oral drug that binds to PAR2, the inflammation-causing properties of this protein were blocked, as were other effects of the high-fat and high-sugar diet, including obesity itself.

Alien limb syndrome: A Bayesian account of unwanted actions. Alien limb syndrome has attracted a wide public interest due its unusual clinical manifestations (e.g., Mosley, 2011).
The term ‘alien limb’ itself implies an enigmatic and dramatic nature of an otherwise debilitating disorder. In the clinical context, alien limb refers to the performance of seemingly purposeful or semi-purposeful movements, which patients report as independent of their own intentions or despite the lack of intention. A Case of Right Alien Hand Syndrome Coexisting with Right-Sided Tactile Extinction. Introduction AHS is a bizarre and very rare neurological movement disorder first described by Goldstein (1908).
Patients with AHS experience one of their limbs as alien, which acts autonomously and performs goal-directed movements that are not guided by the intention of the patient. For example, patients grasp for objects or touch their face without volition. Patients may even act aggressively against themselves. The patient is aware of the discrepancies between intentions and the actions of the hand. AHS has been reported subsequent to lesions in various brain regions, for example supplementary motor area (SMA), anterior cingulate, corpus callosum, anterior prefrontal cortex, posterior parietal cortex, and thalamus (Goldberg et al., 1981; Martí-Fàbregas et al., 2000; Marey-Lopez et al., 2002; Scepkowski and Cronin-Golomb, 2003; Biran and Chatterjee, 2004; Assal et al., 2007; Fitzgerald et al., 2007; Brainin et al., 2008).

If you are among the 5.7 million adults in the United States living with heart failure, a potentially fatal condition, you might have another reason for concern—brain fog, a subtle form of memory loss.1 Certainly, losing your mental alertness is something you’d want to avoid or postpone long into the future. To address this concern, a research team from Emory University initiated a study to explored whether people with heart failure who do brain exercises in combination with aerobic exercise might improve their cognitive losses or lessen the forgetfulness that occurs, often too subtle for most individuals to notice.2.
