The symptoms of Alzheimer's disease include memory loss that impacts daily life, difficulty with familiar tasks, challenges with problem solving or planning, and confusion related to time and place, as detailed by the Alzheimer's Association. Patients may also experience new problems forming words when writing or speaking and have trouble with judging distance and processing visual images.
Individuals with Alzheimer's may repeatedly lose objects, misplace belongings and have difficulty retracing their steps, according to the Alzheimer's Association. The disease also affects judgment and decision making when patients make large purchases or forget to groom themselves on a daily basis. Withdrawal from social activities, leisure engagements and work projects may occur as patients with Alzheimer's disease lose the desire to be social because of memory loss and mental changes that develop. Alzheimer's patients may also become moody or experience changes in personality that include fear, anxiousness, depression, confusion and constant suspicion. Individuals may become suddenly frustrated or upset when they are not in a comfortable or familiar environment.
Disorientation may cause patients with Alzheimer's disease to forget the names of common objects, friends and family members, according to Mayo Clinic. Individuals may also begin to repeat questions and statements without realizing they have already spoken the same words as well as forget events, conversations and appointments.
