nerve cell

When this happens, neurons lose their ability to generate fats needed for energy and normal operation, leading to early and progressively worsening communication problems between nerve cells.

These compounds are known to be highly toxic to nerve cells.

In Parkinson's disease, this protein sticks together into toxic clumps that cause nerve cell death and leads to patients suffering from symptoms such as tremors, difficulties moving and muscle stiffness.

As the nerve cells stop working, swallowing and breathing become more challenging and many people need feeding tubes or breathing apparatus to help them stay alive.

It affects the nerve cells in the brain that control movement, which eventually leads to the loss of the ability to speak, move, swallow and breathe.
