3. What Causes Progressive Supranuclear Palsy?

The exact cause of PSP is not fully understood, but it is associated with the accumulation of a protein called tau in the brain.

Understanding the potential causes and risk factors can help researchers develop better treatments. Need quick and free answers? WHAT.EDU.VN is here to help.

3.1. What Is the Role of Tau Protein in PSP?

Tau is a protein that helps stabilize microtubules in nerve cells, which are essential for cell structure and function. In PSP, tau protein becomes abnormally folded and accumulates in clumps within brain cells. These clumps, known as neurofibrillary tangles, disrupt normal cell function and eventually lead to cell death.

3.2. Which Areas of the Brain Are Affected in PSP?

PSP primarily affects the following areas of the brain:

Brainstem: Controls basic functions such as breathing, heart rate, and eye movements.
Basal Ganglia: Involved in motor control, learning, and executive functions.
