Cerebellum Syndrome
Findings are on the SAME side as the lesion.
Clinical manifestations of cerebellar lesion
• Dyssynergia, dysmetria, dysdiadocokinesia
• Tremor, dysarthria, nystagmus
• Ataxia, tone disorder, pendular movement
• Asthenia - fatigue
• There is no rest tremor but action tremor.
Anatomical classification
1. Vermis cerebelli: The flocculonodular lobe (archioserebellum) is related to the vestibular system.
2. Nuclei cerebelli (nucleus fastigii): It is the main cerebellar nucleus related to the vestibular system
It is examined in three sections in terms of its functions:
1. Vestibulocerebellum: Provides Balance
2. Spinocerebellum: Provides movement and muscle tone
3. Cerebrocerebellum: Provide planning of extremity movements
Cranial Nerve Syndromes
Posterior Cerebral Artery Syndromes
• Its main features are 3 CN being affected.
• If contralateral hemiplegia and mydriasis are together, it is called Weber syndrome.
In lower pons lesions, hemiplegia on the opposite side of the lesion is accompanied by abducens and facial nerve paralysis of the same side (Millard Gubler syndrome)
