Overview of Nervous System Disorders


Nervous Disorders 



Following are unusual of the customary disorders of the nervous system in humans;



➥ Parkinson’s disease

 Epilepsy

➥ Alzheimer’s disease


Parkinson’s disease


Symptoms

It is a nervous disorder, characterized by involuntary tremors, lessened motor power, and rigidity. The thinking flairs are not impaired.


Cause


The sickness is gathered to be caused by cell death in a brain area that produces dopamine. 

The onset of disease

The onset of the sickness is normally in the ’50s and ’60s. The sickness is deliberately progressive; the patient may survive for abundant years.


Cure


The syndrome may emerge from head trauma. Efficient drugs are obtainable such as L- Dopa. A naturally occurring protein known as glial cell-line derived: neurotrophic factor (GDNF) has been shown to boost uptake of dopamine when delivered to lab rats and monkeys. GDNF may be utilized in the near future for humans in the treatment of this disease.


Epilepsy



Symptoms

It is one of the convulsive disorders of nerves that are described by abrupt transient symptoms of motor, sensory, psychic or autonomic nature, frequently associated with changes in consciousness. These changes are supposed to be secondary to sudden transient alterations in brain function associated with excessive rapid electric discharges in the grey matter. 


The onset of disease

Trigger Factors 


In some patient, emotional disturbances play a significant “trigger” role. 

Test

Alzheimer’s disease


Discovery

“Alzheimer’s disease was first characterized by Alois Alzheimer in 1907.” 

Symptoms

It is delineated by a slump in brain capacity. Its symptoms are similar to those sicknesses that cause dementia (memory loss).

Genetic Predisposition

There is a genetic predisposition for the sickness in some people, so it conduces to run in families. 

The onset of disease

There is also proof that high levels of aluminium may contribute to the onset of this disease. There is additionally a slump in brain capacity with age.
