Muscle Weakness Neurological Causes: Symptoms & Treatment

Introduction

It is essential to know the neurological causes of muscle weakness if someone suffers from muscle weakness not due to regular tiredness or overworking of the muscles. Muscle weakness appears due to a failure of proper functioning of the nerves, brain, spinal cord, or muscles. Although sometimes muscle weakness can be temporary, caused by intense physical activity or sickness, other times it could mean the presence of some neurological disease and needs medical attention immediately.

Muscle Weakness: What is it?

Muscle weakness refers to a reduction in the strength of a muscle or muscles. While everyone experiences tiredness at certain times in their lives, muscle weakness can affect someone to the point where even simple tasks like climbing stairs, picking up objects, rising from a chair, or walking can become difficult. Depending on its cause, muscle weakness may be confined to a single area or generalized.

Common Neurological Problems Causing Muscle Weakness

A variety of disorders involving the nervous system can result in muscle weakness. Injury to the brain, spinal cord, nerves, or the link between nerves and muscles inhibits proper functioning of the muscle.

Some of the common neurological problems causing muscle weakness include:

• Stroke

• Multiple sclerosis

• Parkinson’s disease

• Amyotrophic lateral sclerosis (ALS)

• Peripheral neuropathy

• Myasthenia gravis

• Spinal cord injury

• Pinched nerves

• Muscular dystrophy

These neurological disorders differ from each other and hence exhibit distinct symptoms and varying degrees of seriousness.

Symptoms of Neurological Muscle Weakness

The symptoms vary depending on the neurologic disease and the part of the nervous system that is affect. Some people will experience gradual symptoms, while other people will have sudden symptoms.

Some of the symptoms include:

• Having difficulty raising their arms and legs

• Having difficulty walking and climbing stairs

• Falling often

• Loss of balance and coordination

• Numbness and tingling

• Cramping and twitching of the muscles

• Slurred speech

• Difficulty in swallowing

• Fatigue

If the muscle weakness occurs suddenly, especially when accompanied by drooping face or slurred speech, one should seek emergency help since the symptoms can be indicative of stroke.

Diagnosis of Neurological Muscle Weakness

Doctors start by taking a comprehensive patient history and conducting a neurological examination to assess the strength of muscles, reflexes, sensation, and coordination. Depending on the possible causes, further tests can be performed which may involve blood test, MRI scan, CT scan, nerve conduction study, EMG, lumbar puncture, or genetic test.

Treatment Options

The treatment process will depend on the diagnosis made. In some cases of neurological disorders, medications are administered that help minimize swelling or increase nerve functionality. Other diseases will require medication for a prolonged time. Physiotherapy is key in building strength and improving mobility, coordination, and balance. Occupational therapy is crucial in enabling the patient to undertake their day-to-day activities with ease and safety. Surgery might be needed to relieve nerve compression and other spine-related complications. Assisted devices may also help in increasing mobility.

Tips for Lifestyle Changes to Help with Muscle Weakness

Though medications are required to be taken, there are other tips that one could consider as part of his or her lifestyle to manage this condition better. Doing regular physical therapy exercises will keep your muscles strong and flexible. Having a healthy and balanced diet that contains proteins, vitamins, and minerals is another way to stay healthy. Proper sleep and adequate water intake also add up to good neurologic health.

When to Visit a Physician

Visit your doctor immediately in case of sudden onset of muscle weakness on one side of your body along with the inability to speak, see clearly, have a serious headache, or lose balance. You also need to visit a healthcare provider in case of gradual worsening of muscle weakness along with problems in performing daily tasks or along with numbness, pain, or unintentional weight loss.

Conclusion

It is very important to understand neurological causes of muscle weakness since the presence of weakness can indicate a serious disease of the brain, spine, nerve, or muscle. Some diseases include stroke, multiple sclerosis, peripheral neuropathy, and myasthenia gravis, and they need to be properly diagnosed and treated. It can help a person to recover faster, maintain mobility and improve his or her quality of life in general. In case of muscle weakness, a person should visit a neurologist for the proper diagnosis and treatment.
