Hyperreflexia: What It Is, Causes, Symptoms & Treatment - Cleveland Clinic
网页2023年5月9日 · Hyperreflexia happens when your skeletal muscles have an increased or overactive reflex response. A reflex is an involuntary (automatic) action your body does in response to a stimulus. Reflexes protect your body from things that can harm it.
Hyperreflexia - Wikipedia
网页Hyperreflexia is overactive or overresponsive bodily reflexes. Examples of this include twitching and spastic tendencies, which indicate disease of the upper motor neurons and the lessening or loss of control ordinarily exerted by higher brain centers of lower neural pathways (disinhibition).

Hyperreflexia - an overview | ScienceDirect Topics
网页Hyperreflexia indicates an upper motor neuron lesion, and reflects a loss of inhibitory modulation of the motor pathways. It is often associated with increased muscle tone (spasticity). The causative lesion may be anywhere along the pathway of the upper motor neuron in the corticospinal tract, including primary motor cortex, subcortical motor ...
Hyperactive Reflexes: Causes, Symptoms, Diagnosis, and …
网页2024年4月10日 · Hyperactive reflexes, also known as hyperreflexia, refer to an exaggerated response of the body's reflexes to a particular stimulus. These heightened reflexes can indicate an underlying medical condition or neurological issue. In this article, we delve into the causes, symptoms, diagnosis methods, …
Hyperreflexia - an overview | ScienceDirect Topics
网页Hyperreflexia refers to an increased reflex response in the upper or lower extremities, which is considered a sign of involvement of the upper motor neurons in the brain or spinal cord. In the context of preeclampsia, the presence or development of hyperreflexia is indicative of cerebral edema or impending cerebral edema, and is treated with IV ...
Clonus: Definition, Causes, Treatment & Tests - Cleveland Clinic
网页2023年3月16日 · Clonus is an abnormal reflex response that involves involuntary and rhythmic muscle contractions. It’s typically a sign of an upper motor neuron lesion and commonly occurs alongside hyperreflexia, spasticity and muscle weakness. Certain treatments can help manage clonus.

网页Hyperreflexia. A condition of exaggerated deep tendon reflexes. Common causes include upper motor neuron injury (e.g., due to stroke, spinal cord injury, multiple sclerosis), hyperthyroidism, drug reactions (e.g., heroin withdrawal, serotonin syndrome), and …
Hyperreflexia | A Video Atlas of Neuromuscular Disorders
网页Hyperactive deep tendon reflexes (DTRs) is a sign of upper motor neuron (UMN) lesions. It is also commonly seen in normal but anxious people. The proper technique of deep tendon reflex examination and experience play a major role in eliciting and categorizing DTRs.
Hyperreflexia | A Video Atlas of Neuromuscular Disorders
网页Proper technique of reflexes examination and experience play a major role in eliciting and categorizing deep tendon reflexes. Clonus is the highest degree of hyperreflexia. The most important neuromuscular disease associated with hyperreflexia is ALS due to degeneration of the cortical motor neurons.
