Dementia - an irreversible depletion of mental activity with the loss or reduction of knowledge and skills acquired in the past and the impossibility or difficulty of acquiring new ones resulting from past illnesses. In terms of severity, full (total) and partial dementia are distinguished. Complete dementia is characterized by profound impairment of criticism, judgment, memory, unproductive thinking, as well as a careless mood. There is a complete loss of previously characteristic individual character traits inherent in the patient. Complete dementia is observed in Peak's disease, progressive paralysis. With partial dementia, a shallow decrease in criticism, judgment, and memory is more often noted. Low mood prevails with tearfulness, irritability, fatigue. This condition is observed with vascular diseases of the central nervous system, chronic alcoholism, the consequences of traumatic brain injury.
A patient suffering from dementia must be hospitalized for the treatment of the underlying disease, and in advanced cases, for care and supervision, which falls entirely on the shoulders of the middle and junior medical staff.
