One of the first symptoms of Alzheimer’s disease is memory loss, especially short-term memory loss of events and experiences.[1] Other common symptoms of early disease include worsening verbal memory, impaired problem solving, lack of motivation, depression, and sleep disorders. In later stages of disease, memory and cognition continue to worsen, causing disability and deterioration of motor function, in addition to significant personality changes, behavioral changes, and psychosis.
