This chapter presents a case of a 54 year old man Mr. H who had some neurotic personality features associated with some impulsivity. A majority of patients develop neuropsychiatric symptoms, also called behavioral and psychological symptoms of dementia (BPSD) during the course of their illnesses. Neuropsychiatrie symptoms are primary manifestations of the disease process, but other psychological and social factors also play a role in determining which patients will manifest behavioral symptoms. For Mr. H, irritability, anxiety, and delusion are related both to the personal history of the patient and his wife. They are also the consequences of the cognitive deficit and the patient psychological reaction to the perception of his memory loss. Mr. H. has a major loss of self-initiated behavior and interest. However, he is able to respond to external cognitive and emotional stimulation. This helps in choosing the best non-pharmacological strategies.
