The dropped head syndrome with chronic inflammatory demyelinating polyneuropathy

Area of Science:

• Neurology
• Clinical Neuroscience
• Peripheral Nervous System Disorders

Background:

• Dropped head syndrome is a rare condition characterized by weakness of the neck extensor muscles.
• It is associated with several neuromuscular diseases, including motor neuron disease, Parkinson's disease, and myasthenia gravis.
• The syndrome presents a diagnostic challenge due to its varied underlying etiologies.

Observation:

• This report details a case of a female patient experiencing dropped head syndrome.
• The patient was diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP).
• The syndrome emerged as a manifestation of her underlying neurological condition.

Findings:

• The patient's dropped head syndrome was attributed to severe demyelination affecting the nerves innervating the cervical paraspinal muscles.
• This finding highlights a specific pathological mechanism linking CIDP to dropped head syndrome.
• The case underscores the potential for peripheral nerve involvement in causing axial muscle weakness.

Implications:

• This case expands the spectrum of clinical presentations for chronic inflammatory demyelinating polyneuropathy.
• It suggests that dropped head syndrome should be considered in the differential diagnosis of neuromuscular disorders presenting with neck extensor weakness.
• Further research may elucidate the precise relationship between demyelination severity and the occurrence of dropped head syndrome in CIDP patients.
