The study shows how people aged between 18 and 65 with a previous diagnosis of chronic stress and depression were more likely than other people to be diagnosed with mild cognitive impairment or Alzheimer’s disease.

The study suggests that psychiatric conditions like anxiety and depression may be part of a prodromal phase of MS -- a set of preliminary symptoms and clues that arise before classic MS symptoms.

But when this response escalates, for example in the brain, it can lead to serious neurological or psychiatric diseases. A team investigated a marker protein targeted by medical imaging to visualize cerebral inflammation, but whose interpretation was still uncertain. The team reveals that a large quantity of this protein goes hand in hand with a large quantity of inflammatory cells, but its presence is not a sign of their overactivation. These results pave the way for optimal observation of neuroinflammatory processes and a re-reading of previous studies on the subject.

PTSD symptoms are present in up to 40% of trauma survivors in the acute aftermath of trauma, but full-blown PTSD develops in only a small subset of cases. Early identification of those at risk is critical for both early treatment and possible prevention.

Researchers trained 120 volunteers worldwide to suppress thoughts about negative events that worried them, and found that not only did these become less vivid, but that the participants' mental health also improved.

Although the disease is often mischaracterized as a disorder of 'fussiness,' the disorder actually stems from difficulty in processing uncertainty. However, the neural underpinnings of that aberrant processing remains unknown. Now, a new study uses brain imaging to get a closer look at the underpinnings of uncertainty processing in OCD.

But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.

The study used brain imaging to measure the size, or volume, of over 1000 different brain regions.

Experts discuss the relationship between pain, the most common symptom for which individuals visit a physician, and depression and anxiety, the two most prevalent mental health conditions worldwide. Noting the existence of a feedback loop, experts highlight the importance of not neglecting psychological symptoms in patients experiencing pain.

Researchers have now found a correlation between schizophrenia and somatic copy-number variants, a type of mutation that occurs early in development but after genetic material is inherited. This study is one of the first to rigorously describe the relationship between somatic -- not inherited -- genetic mutations and schizophrenia risk.

The authors suggest that, even in the absence of documented evidence, clinicians can use patients' self-reported experiences of abuse and neglect to identify those at risk of developing mental health difficulties and provide early interventions.

Researchers have recently begun making strides toward understanding the neurophysiology underlying different subtypes of depression, which could speed development of better treatments, but much remains to be discovered. Now, a new study identifies multiple subtypes of MDD using brain imaging.

A similar but less pronounced neurochemical imbalance was also detected in healthy individuals with milder compulsive tendencies. Researchers say the findings are a 'major piece of the puzzle' in understanding OCD.

In order to better understand their exact mode of action and undesirable effects, a research team has been working on the question of why different substances in this group of substances have different effects: According to their results the answer lies in the respective binding time of the substances to the dopamine transporter.

The team demonstrated that high-frequency brain waves in the amygdala, a hub for emotional processes, and the hippocampus, a hub for memory processes, are critical to enhancing memory for emotional stimuli. Disruptions to this neural mechanism, brought on either by electrical brain stimulation or depression, impair memory specifically for emotional stimuli.

Fortunately, genomic studies can reveal genes associated with increased risk of certain disorders. In a recent study, researchers from Japan investigated whether the genetic correlations between major psychiatric disorders differed among European and East Asian populations. They showed differences in how bipolar disorders are diagnosed by psychiatrists in the East and the West, which might affect the results of clinical trials.

One might expect that researchers would know how methylphenidate works in the brain by now, but little is known about the drug's mechanism of action. Now, a new study seeks to close this gap and understand how methylphenidate interacts with cognitive control networks and attentional behavior.

Neurologists have revealed changes to a brain mechanism used for learning and survival may play a role in how someone responds to a threat following a traumatic experience. Another study found that another mechanism responsible for emotion and memory is impacted and may make it difficult for someone with PTSD to discriminate between safety, danger, or reward. It overgeneralizes towards danger. These findings could significantly advance future treatments. Wed, 07 Dec 2022 14:22:55 EST //www.koonmotors.com/releases/2022/12/221207142255.htm
