Darkness in front of eyes and sudden shivering body while standing are the symptoms which disease?

Parkinson's disease

Parkinson's disease is a neurodegenerative disorder that affects the central nervous system. It is characterized by a loss of nerve cells in the brain that produce the neurotransmitter dopamine. This loss of dopamine leads to a variety of symptoms, including:

- Tremors

-Rigidity

-Bradykinesia

-Postural instability

-Difficulty with balance

-Speaking softly or in a monotone voice

-Depression

-Anxiety

-Sleep problems

-Memory loss

-Difficulty with attention and concentration

Darkness in front of eyes (visual hallucinations) and sudden shivering body (orthostatic hypotension) are two of the less common symptoms of Parkinson's disease. Visual hallucinations occur when the brain misinterprets signals from the eyes, leading to the perception of things that are not actually there. Orthostatic hypotension occurs when blood pressure drops suddenly when a person stands up from a sitting or lying position. This can cause dizziness, lightheadedness, and even fainting.

If you are experiencing darkness in front of eyes and sudden shivering body while standing, it is important to see a doctor to rule out Parkinson's disease and other possible causes.
