Objective This study aimed to describe the behavioral and psychological symptoms of patients with different types of dementia and to correlate these symptoms to demographic and clinical variables of dementia such as age, sex, and score of cognitive assessment scales. Patients and methods This study was carried out on 73 patients with dementia. Patients were classified into three groups: patients with Alzheimer dementia, patients with vascular dementia, and patients with mixed dementia. Cognitive evaluation of the three groups was performed by the Mini Mental State Examination and Clock Drawing Test. The neuropsychiatric inventory was used to assess behavioral and psychological symptoms. Daily activities were assessed using Activities of Daily Living and The Lawton Instrumental Activities of Daily Living. Results Apathy depression, and sleep disturbances were most prevalent in Alzheimer dementia, whereas depression, anxiety, and apathy were most prevalent in vascular dementia and in the miscellaneous group. There was a highly statistical difference between the three groups as regards depression and anxiety (P≤0.0001). Duration of illness correlated negatively with the scores of Mini Mental State Examination (P<0.001), Clock Drawing Test (P<0.001), Activity of the Daily Living (P<0.001), and the Lawton Instrumental Activities of Daily Living scores (P=0.003). Severity of the symptoms was higher in the miscellaneous group of dementia and lower in the Alzheimer group (P<0.001). Conclusion Apathy, depression, anxiety, and sleep disturbances were the most prevalent psychiatric symptoms. The severity of the symptoms was lower in the Alzheimer group and worse in the miscellaneous group. There was a positive correlation between the cognitive function and the functionality of those patients.
