Jackson's Syndrome

Jackson's Syndrome (pronounced: /ˈdʒæksənz ˈsɪndroʊm/) is a rare neurological disorder characterized by a combination of cranial nerve palsies and contralateral hemiplegia.

Etymology

The syndrome is named after the British neurologist, John Hughlings Jackson, who first described the condition in the late 19th century.

Definition

Jackson's Syndrome is a neurological condition that results from a lesion at the base of the pons, a part of the brainstem. This lesion affects the exiting root fibers of the trigeminal nerve and the abducens nerve, as well as the pyramidal tract fibers, leading to a unique combination of symptoms.

Symptoms

The symptoms of Jackson's Syndrome include:

• Ipsilateral loss of facial sensation due to damage to the trigeminal nerve
• Diplopia (double vision) and abducens palsy due to damage to the abducens nerve
• Contralateral hemiplegia affecting the body below the head due to damage to the pyramidal tract
