Hemifacial hyperhidrosis associated with ipsilateral/contralateral cervical disc herniation myelopathy. Functional
Functional Neurology
|July 12, 2014
Summary
Compensatory hemifacial hyperhidrosis can occur due to cervical disc herniation affecting thermoregulation. This study investigates the link between neck issues and sweating abnormalities, aiding diagnosis.
Area of Science:
- Neurology
- Dermatology
- Physiology
Background:
- Thermoregulation is vital, but hyperhidrosis (excessive sweating) can be problematic.
- Cervical disc herniation can disrupt normal bodily functions.
Observation:
- Five patients presented with hemifacial hyperhidrosis.
- Symptoms included sweating on one side of the face without other neurological signs like anisocoria or blepharoptosis.
- Sweat function testing and thermography confirmed localized hyperhidrosis.
Findings:
- Neck MRI revealed cervical disc herniation in all patients.
- Lateral compression correlated with ipsilateral hypohidrosis below hyperhidrosis.
- Paramedian compression was associated with contralateral hyperhidrosis and hypohidrosis.
- No intraspinal pathological signal intensity was observed on MRI.
Implications:
- Cervical disc herniation can cause compensatory hemifacial hyperhidrosis.
- Lateral dural or paramedian compression may affect sudomotor pathways or related blood supply.
- Diagnostic tools like sweat testing, thermography, and MRI are crucial for identifying the cause of sweating abnormalities and associated myelopathy.

Herniated Intervertebral Disc l: Introduction
32
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Degenerative Disc Disease ll: Pathophysiology
21
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

Increased Intracranial Pressure ll: Pathophysiology
15
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins...

Degenerative Disc Disease I: Introduction
24
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Disorders of the Autonomic Nervous System
1.8K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Cardiomyopathy III: Hypertrophic Cardiomyopathy
801
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
