Cognitive disorders

progressive, neurodegenerative disease characterized by memory loss

Dementia is a syndrome, often associated with neurodegenerative diseases such as Alzheimer's, and characterized by a general decline in cognitive abilities that affects a person's ability to perform everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Dementia is an incurable, prog

Amnesia is a deficit in memory caused by brain damage or brain diseases, but it can also be temporarily caused by the use of various sedative and hypnotic drugs. The memory can be either wholly or partially lost due to the extent of damage that is caused.

Delirium (formerly acute confusional state, an ambiguous term that is now discouraged) is a specific state of acute confusion attributable to the direct physiological consequence of a medical condition, effects of a psychoactive substance, or multiple causes, which usually develops over the course of hours to days. As a syndrome, delirium presents with disturbances in attention, awareness, and higher-order cognition. People with delirium may experience other neuropsychiatric disturbances including changes in psychomotor activity (e.g., hyperactive, hypoactive, or mixed level of activity), disr

thumb|Frontal lobe (in blue)/Lobes of the brain Paratonia is the inability to relax muscles during muscle tone assessment. There are two types of paratonia: oppositional and facilitatory. Oppositional paratonia ("gegenhalten") occurs when subjects involuntarily resist passive movements, while facilitatory paratonia ("mitgehen") occurs when subjects involuntarily assist with passive movements. Both types of paratonia have been associated with cognitive impairment or mental disorders, particularly in relation to frontal lobe dysfunction. Paratonia is frequently encountered in association with d
