the average life expectancy
following diagnosis is three to nine

The cause of Alzheimer's disease• is poorly understood. About 70% of the risk is believed to
be genetic with many genes usually involved• There are no medications or supplements that decrease
risk. No treatments stop or reverse its progression, though some may temporarily improve symptoms

pharmaceutical psychosocial caregiving.

Parkinson’s disease
Is a degenerative disorder of the central nervous system mainly affecting the motor system. The motor symptoms
of Parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the
midbrain.

Signs and symtoms
Parkinson's disease affects movement, producing motor symptoms. Non-motor symptoms, which include autonomic dysfunction, neuropsychiatric problems (mood, cognition, behavior or thought alterations), and sensory and sleep difficulties, are also common.

Early in the course of the disease
the most obvious symptoms are movement-related these include shaking, rigidity, slowness of movement and difficulty with walking and gait.

Later, thinking and behavioral problems may arise, with dementia commonly occurring in the advanced stages of the disease, and depression is the most common psychiatric symptom. Other symptoms include sensory, sleep and emotional problems.

Primary Parkinson's disease is referred to as idiopathic (having no known cause), although some atypical cases have a genetic origin
secondary parkinsonism is due to known causes like toxins
The disease can be either primary or secondary

ComplementosThere is no cure for Parkinson's disease, but medications,
surgery and multidisciplinary management can provide relief from the symptoms. The main families of drugs useful
for treating motor symptoms are levodopa
