In brief: Full body convulsion

Involves both arms/legs with loss of consciousness.
Tonic phase is stiffness; clonic phase involves jerking of arms/legs. Associated with tongue biting/loss of urine. May be due to genetic factors (involves both sides of brain at onset) or acquired factors (e.g. Stroke, but others) (starts in one place of brain and spreads). Usually lasts up to 90 seconds. Very treatable.

In brief: Seizure: entire body

It can occur in people of any age.
They may occur once (single episode), or as part of a repeated, chronic condition (epilepsy).Many have vision, taste, smell, or sensory changes, hallucinations, or dizziness before the seizure (aura). Seizures involve muscle rigidity, followed by violent muscle contractions, and loss of alertness (consciousness).
