Neurological worsening, cerebral hemorrhage, and brain edema were the most common severe effects. However, repinotan was generally shown to be safe. [16]
Extrapyramidal symptoms (EPS) are symptoms that are archetypically associated with the extrapyramidal system of the brain's cerebral cortex. When such symptoms are caused by medications or other drugs, they are also known as extrapyramidal side effects (EPSE). The symptoms can be acute (short-term) or chronic (long-term).
Unlike many effects of stroke, where the clinician is able to judge the particular area of the brain that a stroke has injured by certain signs or symptoms, the causation of apraxia is less clear. A common theory is that the part of the brain that contains information for previously learned skilled motor activities has been either lost or ...
Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into the ...
