Parkinson’s disease (PD) is a brain disorder that leads to shaking (tremors) and difficulty with walking, movement, and coordination. PD encompasses a variety of syndromes, all of which are progressive and degenerative.
Dementia is a syndrome that involves memory loss and decline in intellectual functioning that is severe enough to interfere with an individual’s ability to perform routine tasks.
Epilepsy is a brain disorder in which the patient experiences repeated, unpredictable seizures, or episodes of disturbed brain activity that cause changes in attention or behavior.
Alzheimer’s disease is an irreversible and progressive disease which slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living.
