Loss of touch with reality: Patients with Alzheimer's may become suspicious or paranoid. About half of patients experience delusions: beliefs that do not correspond to reality. Because of paranoia and suspicion, patients may think they have been robbed or that their caregivers or partners are lying to them. Hallucinations are also a common symptom.
Difficulties with daily activities: Activities that were once natural become difficult and awkward. At the same time, normal social interactions may remain intact for a long time. Thus, the outside world might think that everything is fine.
