Akinetic mutism: a report of three cases
Acta Neurologica Scandinavica
|January 6, 1999
Summary
Three cases of akinetic mutism, characterized by immobility and preserved alertness, were linked to specific brain lesions. Findings highlight the globus pallidus and prefrontostriatal circuits
Area of Science:
- Neurology
- Neuroscience
Background:
- Akinetic mutism is a syndrome of profound psychomotor arrest with preserved consciousness.
- Understanding the neuroanatomical correlates of akinetic mutism is crucial for diagnosis and management.
Observation:
- Reported are three distinct cases of akinetic mutism.
- Case 1 involved bipallidal necrosis.
- Case 2 presented with left pallidal necrosis and right frontoparietal infarction.
- Case 3 showed left striato-capsular infarction with obstructive hydrocephalus.
Findings:
- Lesions in the globus pallidus and striato-capsular regions were identified in the cases.
- The findings suggest a link between these basal ganglia structures and the manifestation of akinetic mutism.
- Specific patterns of infarction and necrosis correlate with the clinical syndrome.
Implications:
- This study underscores the critical role of the globus pallidus and associated prefrontostriatal circuits in voluntary movement initiation.
- The results contribute to the understanding of the pathophysiology of akinetic mutism.
- Further research into these circuits may reveal novel therapeutic targets.

01:20Myasthenia Gravis: Overview and Treatment
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

01:15Myasthenia Gravis: Diagnostic Tests
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

01:31Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
01:28Disorders of the Skeletal Muscle
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

01:12Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
01:11Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
