About Parkinson's disease
signs,cause and treatment
What is Parkinson's disease?
Parkinson's disease is a brain disorder that causes a gradual loss of muscle control. It is characterized by the destruction of dopaminergic neurons from the black substance. The symptoms of Parkinson's tend to be mild at first and can sometimes be overlooked. Parkinson's was originally called a "shaking palsy," but not everyone with Parkinson's has a tremor.
The loss of dopamine in Parkinson's disease
What is dopamine?
Dopamine is a neurotransmitter. It is a chemical messenger that helps in the transmission of signals in the brain and other vital areas
Dopamine allows messages to be sent to the parts of the brain that co-ordinate movement.
With the loss of dopamine, these parts of the brain are unable to work normally, causing the symptoms of Parkinson's to appear.
Symptoms of Parkinson's disease
The early signs of Parkinson's may be subtle and they include:
- Slight shaking of a finger, hand, leg, or lip
- Stiffness or difficulty walking
- Difficulty getting out of a chair
- A 'masked' face, frozen in a serious expression
- Stooped posture
- Sleep disorders
