Generalised tonic-clonic seizure
• loss of consciousness
• ‘epileptic cry’
• fall (injury)
• tonic phase then clonic jerking
• tongue biting, incontinence, cyanosis
• sudden onset, gradual recovery
• post-ictal confusion, sleep,
headache, muscle pain
• aura/partial features if SGS
1. Idiopathic generalised
epilepsies
2. Symptomatic generalised
epilepsies with wide range
underlying pathology

Generalised absence seizure
• blank stare
• loss of consciousness
• cessation of motor activity
• blinking, eye rolling, minor tone change
• sudden onset, rapid recovery
• brief, many attacks per day
• usually in IGE
• generalised spike and wave discharge
![Page 11: Faints, fits and funny turns - londonscn.nhs.uk · Faints, fits and funny turns Dr Dominic Heaney Consultant neurologist and honorary senior lecturer ULCH NHS Foundation Trust National](https://reader033.vdocument.in/reader033/viewer/2022042915/5f5295056df5752592684b5a/html5/thumbnails/11.jpg)
Simple partial seizures
• no alteration in consciousness
• no amnesia
• sudden onset and cessation
• focal symptoms or signs:
motor
sensory and special sensory
psychic (dysmnestic, cognitive, affective,
hallucinations, illusions)
• reflect anatomical origin of the seizure
• due to focal cortical pathology
![Page 12: Faints, fits and funny turns - londonscn.nhs.uk · Faints, fits and funny turns Dr Dominic Heaney Consultant neurologist and honorary senior lecturer ULCH NHS Foundation Trust National](https://reader033.vdocument.in/reader033/viewer/2022042915/5f5295056df5752592684b5a/html5/thumbnails/12.jpg)
Complex partial seizures
• Temporal lobe 60%
• Extra-temporal 40%
(mostly frontal lobe)
![Page 13: Faints, fits and funny turns - londonscn.nhs.uk · Faints, fits and funny turns Dr Dominic Heaney Consultant neurologist and honorary senior lecturer ULCH NHS Foundation Trust National](https://reader033.vdocument.in/reader033/viewer/2022042915/5f5295056df5752592684b5a/html5/thumbnails/13.jpg)
Temporal lobe seizure
• aura (as SPS: visceral, dysmnestic), brief
• altered consciousness
• amnesia
• automatism (oro-alimentary, gestural, verbal)
• sudden onset, gradual recovery
focal spikes
rhythmic ictal discharge
![Page 14: Faints, fits and funny turns - londonscn.nhs.uk · Faints, fits and funny turns Dr Dominic Heaney Consultant neurologist and honorary senior lecturer ULCH NHS Foundation Trust National](https://reader033.vdocument.in/reader033/viewer/2022042915/5f5295056df5752592684b5a/html5/thumbnails/14.jpg)
Frontal lobe CPS
• brief stereotyped seizures
• frequent attacks with clustering
• nocturnal +
• sudden onset and cessation
• complex bilateral motor automatisms
• secondary generalisation
• interictal and ictal EEG variable
![Page 15: Faints, fits and funny turns - londonscn.nhs.uk · Faints, fits and funny turns Dr Dominic Heaney Consultant neurologist and honorary senior lecturer ULCH NHS Foundation Trust National](https://reader033.vdocument.in/reader033/viewer/2022042915/5f5295056df5752592684b5a/html5/thumbnails/15.jpg)
Other extra-temporal partial seizures
Central Contralateral jerks (march)
Contralateral sensory
Posturing
EEG often normal
Parietal Somatosensory
Illusion of change in body size/shape
Vertigo
Gustatory
Occipital Elementary visual hallucinations
Visuo-spatial distortion
Amaurosis
Head turning (usually adversive)
Eyelid flutter, blinking, nystagmus
May propagate to adjacent
cortical regions
EEG : focal / non-localised /
anterior
