Gelastic seizures, marked by bouts of uncontrollable laughter, are classically linked to hypothalamic hamartomas. They may also be associated with Pallister-Hall syndrome (caused by a GLI3 mutation on chromosome 7). Present in infancy. EEG often normal due to deep seizure focus.

من وقتها تغيّر عالم الـStroke بشكل جنوني: صار الـCTA/CTP جزء أساسي من تقييم الجلطات الحادة، دخل الـTenecteplase بقوة، وفي 2015 تغيّر كل شيء مع ثورة الـMechanical Thrombectomy.
An easy way to differentiate these midbrain syndromes is to remember that, moving from anterior to posterior, all three involve oculomotor nerve damage, with additional distinct features:
Weber’s syndrome – affects the anterior midbrain, involving the corticospinal tracts, leading to contralateral weakness.
Benedikt’s syndrome – involves the mid-midbrain, including the red nucleus, causing abnormal involuntary movements such as tremor and chorea.
Claude’s syndrome – localized to the posterior midbrain, where superior cerebellar peduncle fibers (after decussation) are affected, resulting in cerebellar signs (think Claude = Cerebellar).
