Abstract:
Subacute sclerosing panencephalitis is a devastating neurodegenerative disorder characterized by cognitive and memory deterioration, personality changes, behavior abnormalities, and a steady motor decline. Extrapyramidal manifestations are commonly seen in the advanced stage of the disease. We discuss a 10-year-old boy with subacute sclerosing panencephalitis presenting with generalized choreoathetosis, myoclonus, and cognitive decline. He had not been immunized for measles. His elder sister had a viral exanthematous illness 4 years ago. Magnetic resonance imaging revealed bilateral, asymmetric putaminal hyperintensities. A diagnosis of subacute sclerosing panencephalitis was confirmed by periodic complexes in the electroencephalograph and elevated antimeasles antibody titers in the blood and cerebrospinal fluid (1:625). Our case highlights that atypical clinical and radiological features of subacute sclerosing panencephalitis should always be borne in mind in children from endemic areas. Generalized choreoathetosis and bilateral putaminal involvement in the index case add to the spectrum of atypical presentations of subacute sclerosing panencephalitis in children.

Peripheral Nervous System: Ganglia and Nerves
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
Sympathetic Pathways: Sympathetic Chain Ganglia
Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
