Intervention for several behavioural disorders in Alzheimer's-type dementia

In Alzheimer's-type dementia, significant nerve cell degeneration is seen in the medial temporal lobe, including the hippocampal region, and in the temporoparietal association area. As symptoms progress, impairments in various behaviours begin to occur in daily life. In particular, higher brain dysfunction, including parietal association area dysfunction, are major impediments to providing care or rehabilitation. Herein, we explain behavioural disorders stemming from higher brain dysfunction and discuss the methodology in providing specific care and appropriate rehabilitation. To provide appropriate rehabilitation, it is important to properly assess the causes of behavioural disorder by organizing the characteristics of symptoms, the person and the environment.
