EPILEPSY - PART 1

A Seizure is an abnormal Electrical activity in the brain that produces symptoms.
Epilepsy is diagnosed when a person suffers from repeated Seizures.

PRIMARILY THERE ARE 4 TYPES OF SEIZURES

1. GTCS - Grand Mal Epilepsy & Myoclonic Epilepsy - GTCS causes vigorous muscle movements throughout the body (Convulsions) and then a person passes out/ looses counsciousness. In some other variants of this seizure type a person either directly passes out or falls repeatedly or undergoes rigid and tonic posturing of body muscles during a seizure attack.

Myoclonic Epilepsy causes jerky movement of a particular muscle group rather than the whole body.
Hence, the above two types of seizures can be easily identified owing to the external movements they produce that are visible to any observer.

2. Partial Epilepsy (Focal Seizure) - This involves a focal part of the brain from where an electrical activity could arise and lead to episodic neurological symptoms (a symptom that comes and goes)
The symptom could be - Motor, Sensory, Psychic, or Autonomic.

3. Absence Seizures - Petit Mal Epilepsy. This seizure type only causes a brief change in consciousness where the seizing person may be observed as being lost or staring. It is most difficult to spot but an EEG could help diagnose it.

4. Psychogenic Seizures - This seizures occur purely because of mental stress. The person usually is unaware of the psychological stress but is aware of the physical symptom of a seizure.
