Examples of neurological conditions that can cause muscle weakness include: Neurological conditions are often progressive, which means that they get worse over time. If myelopathy is suspected, MRI can detect lesions in the spinal cord. This can produce muscle weakness. Factors may include the following: Muscle weakness (eg, caused by stroke, use of certain drugs, myelopathy due to cervical spondylosis, or muscle atrophy), Age-related loss of neural networks mediating postural stability (vestibular system, proprioceptive pathways), coordination (cerebellum, basal ganglia), vision, and praxis (frontal lobe).

However, upper motor neuron dysfunction can decrease tone and reflexes if motor paralysis is sudden and severe (eg, in spinal cord transection, in which tone first decreases, then increases gradually over days to weeks) or if the lesion damages the motor cortex of the precentral gyrus and not nearby motor association areas. Many disorders (eg, chronic inflammatory demyelinating polyneuropathy Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) Chronic inflammatory demyelinating polyneuropathy is an immune-mediated polyneuropathy characterized by symmetric weakness of proximal and distal muscles and by progression continuing > 2 months read more , Guillain-Barr syndrome Guillain-Barr Syndrome (GBS) Guillain-Barr syndrome is an acute, usually rapidly progressive but self-limited inflammatory polyneuropathy characterized by muscular weakness and mild distal sensory loss. There is a problem with Electrolyte imbalance [Fact sheet]. Muscle weakness can also be caused by low levels of potassium and other electrolytes within muscle cells.

Proximal myopathy presents as symmetrical weakness of proximal upper and/or lower limbs. Double vision (diplopia) is uncommon. Walking on the toes and heels is tested; distal muscle weakness makes these maneuvers difficult. Evaluation of weakness should try to distinguish true muscular weakness from fatigue, then check for findings that help establish the location or mechanism (eg, whether weakness is caused by dysfunction of the brain, spinal cord, plexuses, peripheral nerves, neuromuscular junction, or muscles) and, when possible, the cause. The cause of autoimmune myositis seems to be an autoimmune reaction to muscle tissue in genetically susceptible people. All rights reserved.

Problems with kidney function can cause metabolic waste products, such as creatinine, to build up in the muscles. The location of certain lesions correlates with physical findings: Upper motor neuron dysfunction disinhibits lower motor neurons, resulting in increased muscle tone (spasticity) and increased muscle stretch reflexes (hyperreflexia). When the brachial or lumbosacral plexus is damaged, motor, sensory, and reflex deficits are often patchy and do not follow any one peripheral nerve pattern. CALF OR ACHILLES PROBLEMS?

FOIA If a persons muscle weakness is not due to any of the issues above, or if they have particular risk factors, a doctor may consider rare causes when making their diagnosis. They may also report limb heaviness or stiffness. In muscular dystrophy, abnormal genes (mutations) interfere with the production of proteins needed to form healthy muscle. Polymyositis (dermatomyositis). Weakness is loss of muscle strength, although many patients also use the term when they feel generally fatigued or have functional limitations (eg, due to pain or limited joint motion) even though muscle strength is normal. Fundoscopy (retinitis pigmentosa, retinal telangiectasia in FSH) Urine myoglobin (McArdle's disease) Differential diagnosis If no symptoms or signs of true weakness (eg, characteristic anatomic and temporal pattern, objective signs) are present and patients complain only of overall weakness, fatigue, or lack of energy, clinicians should consider nonneurologic disorders.
