A crisp explainer on how seizures present and how they differ from look-alikes. Dr Prabhu defines a seizure (“a transient episode of abnormal, excessive, hypersynchronous neuronal activity”) and walks through focal onset signs (one hand/face/eye twitch, localized sensations), generalized onset (GTCS), common motor subtypes (tonic, clonic, myoclonic, atonic/astatic), non-motor phenomena (sensory, visual, auditory, smell, taste), absence seizures, and PNES (pseudo-seizures) often seen in teens/young adults—stressing the need for proper clinical evaluation.
Chapters (08:03)
00:00 What is a seizure? The core definition and brain basis.
00:35 Focal onset: one area starts (hand/mouth/eye); brain controls the whole body.
01:25 Generalized onset (GTCS): whole-body pull/jerks; overview.
02:10 Motor subtypes: tonic, clonic, myoclonic, atonic/astatic—how movements look.
03:05 Non-motor features: sensory, visual, auditory, smell, taste.
03:45 Absence seizures: brief staring episodes.
04:30 PNES (pseudo-seizures): what they are, who’s affected, and why to assess carefully.
05:40 Movement patterns & clues clinicians look for.
06:45 Recap: focal vs generalized vs absence vs PNES.
07:25 What’s next in the series & sign-off.
Key Takeaways
• Definition matters: seizures are bursts of abnormal, hypersynchronous brain activity.
• Types: focal onset, generalized (GTCS), absence; motor and non-motor variants.
• PNES are seizure-like events with psychological origin—require expert evaluation to avoid misdiagnosis.
