Summary
Hand tremor was found in 40% of hemifacial spasm (HFS) patients, unlike other movement disorders. This tremor
Area of Science:
- Neurology
- Movement Disorders
Background:
- Tremor commonly co-occurs with dystonia and other movement disorders.
- No prior reports documented tremor in patients with hemifacial spasm (HFS).
Purpose of the Study:
- To investigate the occurrence, type, and characteristics of tremor in individuals with HFS.
- To compare tremor prevalence in HFS patients versus healthy controls.
Main Methods:
- Clinical and objective assessment of tremor using triaxial accelerometer and EMG.
- Inclusion of 47 HFS patients and 48 age/sex-matched healthy volunteers.
- Utilized a load test and Clinical Global Impression-Severity (CGI-S) scale.
Main Results:
- Tremor was detected in 40% of HFS patients and 10% of controls.
- Identified various tremor types in HFS patients, including essential and psychogenic tremor.
- Hand tremor occurrence correlated with increased HFS severity (CGI score).
Conclusions:
- Hand tremor is a notable comorbidity in a significant portion of HFS patients.
- The etiology of tremor in HFS patients remains unclear but may involve medullary compression.
- Further research is needed to understand the tremor-HFS relationship.

Alterations 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...
Alterations 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...
Tetanus
Tetanus is a life-threatening neurological disorder characterized by persistent muscle contractions and spastic paralysis. It is caused by Clostridium tetani, a motile, Gram-positive, rod-shaped, obligate anaerobe. These bacteria produce terminal endospores, giving them a distinctive “lollipop” or “tennis-racket” appearance. They thrive in anaerobic environments, such as those found in deep puncture wounds.Once introduced into the body, the spores germinate into vegetative cells. These cells...
Vascular Spasm
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Parkinson's Disease: Treatment
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of its...
