Dr. Alzheimer is revered by scientists not just for his ground-breaking description of a serious illness, but also as a role model. He created a new benchmark for comprehending neurodegenerative illnesses by developing a deep therapeutic interaction with his patients and using innovative scientific methods to assess how symptoms connected to physical brain changes manifest.

The nerve cells collaborate to carry out all the communications required for cognitive processes such as thinking, learning, remembering, and planning.

These plaques and tangles impede the connection between nerve cells, preventing them from performing their functions. Alzheimer's disease symptoms are caused by the gradual and progressive loss of nerve cells, which begins in one region of the brain and spreads to others.
