Neuropsychiatric disorder is a blanket medical term that encompasses a broad range of medical conditions that involve both neurology and psychiatry. Common neuropsychiatric disorders include: seizures. attention deficit disorders. Neuropsychiatric symptoms are a common accompaniment of dementia. These include agitation, depression, apathy, delusions, hallucinations, and sleep impairment. Neuropsychiatric diseases, such as schizophrenia, depression and autism, are a huge burden on society, impairing the health of those affected, as well as their ability to learn and to work. Stress can cause an imbalance of neural circuitry subserving cognition, decision making, anxiety and mood that can increase or decrease expression of those behaviors and behavioral states. This imbalance, in turn, affects systemic physiology via neuroendocrine, autonomic, immune and metabolic mediators.
