Partial Complex Seizure.

Question 1

An 8 YO boy developed a seizure firstly affecting his arm that lasted for
several minutes. During the whole episode, he was unconscious and unable to
remember the events that led to his seizure. CT scan of head shows a lesion
on the left cerebral hemisphere.

Answer 1

The type of seizure → Partial Complex Seizure.
The likely cause of seizure → Space-occupying lesion (seen on the CT).
√ Affecting his arm (a part of the body) → Focal (Partial).
√ Loss of Consciousness → Complex.
√ Partial complex means there is something blocking a part of one cerebral
hemisphere which is compatible with the CT finding → A space occupying
lesion.
