Key Symptoms
Alzheimer's disease typically begins gradually and worsens over time. The following symptoms can help identify it:
- Memory loss: The most common symptom is difficulty retaining new information, such as recent events or conversations. Problems with reading, speaking, writing, and arithmetic may also emerge.
- Cognitive decline: The ability to think, make decisions, and understand gradually diminishes. Taking initiative and acting independently becomes challenging. Social skills deteriorate, and disorientation regarding time or place may occur.
- Loss of touch with reality: Patients may become suspicious or paranoid. About half experience delusions—beliefs that conflict with reality. Paranoia can lead to accusations of theft or deceit by partners or caregivers. Hallucinations are also frequent.
- Difficulty with daily tasks: Routine activities become increasingly difficult and clumsy. However, social relationships often remain intact for a long time, so the condition may not be obvious to outsiders.
