Paralysis is the loss or impairment of voluntary muscular power. Paralysis can result from either diseases involving changes in the makeup of nervous or muscular tissue or those that are the result of metabolic disturbances that interfere with the function of nerves or muscles. Depending upon the cause, paralysis may affect a specific muscle group or region of the body, or a larger area may be involved. When only one side of the body is affected, the condition is known as hemiplegia. In other instances, both sides of the body may suffer the effects, leading to diplegia or bilateral hemiplegia. When only the lower limbs are affected by paralysis, it is called paraplegia. When all four limbs are affected, it is referred to as quadriplegia. The term palsy is sometimes used to refer to the loss of muscle power in a body part.
Other causes of paralysis
- Alternating Hemiplegia
- Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP)
- Familial Periodic Paralysis
- Hereditary Spastic Paraplegia
- Muscular Dystrophy
- Tick Paralysis
- Todd's Paralysis

Adenoid Cystic Carcinoma (ACC)
Adenoid cystic carcinoma is a rare cancer that forms in glandular tissues. The location of the cancer determines the signs and symptoms. Treatment might incorporate chemotherapy, surgery, and/or radiation therapy.
Alcoholism and Alcohol Abuse
Alcoholism is a disease that includes alcohol craving and continued drinking despite repeated alcohol-related problems, such as losing a job or getting into trouble with the law. It can cause myriad health problems, including cirrhosis of the liver, birth defects, heart disease, stroke, psychological problems, and dementia. Counseling and a few medications can be effective for alcoholism treatment.
ALS (Amyotrophic Lateral Sclerosis) Symptoms, Causes, Life Expectancy
Amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease) is a neurological disease that progresses rapidly. The disease attacks the nerve cells responsible for the control of voluntary muscles. Early symptoms include cramping, twitching, or stiffness of the muscles; slurred nasal speech; difficulty swallowing or chewing, and muscle weakness in an arm or leg. Currently, the cause of ALS is not known. ALS is a fatal disease. No cure has been found for ALS, however, the drug riluzole (Rilutek) is FDA approved, and this drug reduces the damage to motor neurons by decreasing the release of glutamate.
Bell's Palsy (Facial Nerve Problems)
Bell's palsy is one type of facial nerve paralysis. The seventh cranial nerve controls the muscles of the face, and although scientists do not know the exact cause of Bell's palsy, they think it may be due to nerve damage from an infection, for example, the flu, common cold viruses, and more serious infections like meningitis. The symptoms of Bell's palsy vary from person to person, but can include mild weakness to total paralysis, dry eye, dry mouth, eyelid drooping, drooling, mouth drooping, dry mouth, changes in taste, and excessive tearing in one eye.
A birthmark is any abnormal mark, spot, or bump that is present in or around the time of birth on the skin of an infant. Types of birthmarks include cafe au lait marks, Mongolian spots, strawberry marks, and others. Depending on the birthmark type, birthmarks can be removed by scalpel surgery, lasers, and rarely radiation.
Botulism is an illness caused by a neurotoxin produced by the bacterium Clostridium botulinum. There are three types of botulism: food-borne, wound, and infant. Symptoms include muscle paralysis, dry mouth, constipation, slurred speech, and blurred vision. If food-borne and wound botulism are detected early enough, they may be treated with an antitoxin.
Brain Damage: Symptoms, Causes, Treatment
Brain damage causes destruction or deterioration of brain cells. Traumatic brain injury (TBI) and acquired brain injury (ABI) are two kinds of brain damage. Symptoms may include headaches, confusion, memory problems, nausea, and more. Treatment includes patient stabilization and ensuring that blood and oxygen are flowing to the brain. Adequate blood pressure control is also necessary. In cases of severe brain damage, surgery and rehabilitation may be required.
Brain Lesions (Lesions on the Brain)
A brain lesion is defined as an area of damaged brain. Brain lesions (lesions on the brain) are caused by trauma, inflammation, autoimmune diseases, cancers, other diseases, stroke, bleeding, pituitary adenomas, and cerebral palsy. Symptoms of brain lesions include headache, nausea, fever, neck pain and stiffness, affected vision and speech, and weakness or paralysis to one side of the body. Diagnosis of brain lesions is generally accomplished with imaging studies like CT or MRI scans. Treatment and prognosis of brain lesions depends on the cause of the lesion.
Cauda Equina Syndrome
Cauda equina syndrome is a medical emergency condition that is caused by the uncommon compression of the nerves at the end of the spinal cord. Symptoms of cauda equina syndrome include lower back pain, tingling and/or numbness in the buttocks and lower extremities, bowel or bladder incontinence, and weakness in the legs. Causes of cauda equina syndrome include herniated discs, hematomas, or infection. Treatment is generally prompt surgery.
Cerebral palsy (CP) is an abnormality of motor function and postural tone acquired at an early age (even before birth). Cerebral palsy is generally caused by brain trauma. Types of cerebral palsy include: spastic, dyskinetic (dystonic or choreoathetoid), hypotonic, and mixed types. There is no cure for cerebral palsy, and treatment is generally managing the symptoms of the condition.
Does NMO Cause Fatigue?
Neuromyelitis optica (NMO) or Devic disease is a rare, autoimmune disease of the central nervous system (brain and spinal cord). Neuromyelitis optica (NMO) doesn't cause fatigue, but living with the disease can lead to fatigue.
Does NMO Show on MRI?
Neuromyelitis optica (NMO) or Devic disease is a rare, autoimmune disease of the central nervous system (CNS). Magnetic resonance imaging (MRI) is the choice of diagnostic method for neuromyelitis optica (NMO).
Drug Abuse and Addiction
Drug abuse and addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
Guillain-Barré syndrome is an autoimmune disease of the nervous system due to damage to the myelin sheath around nerves. It is the most acquired nerve disease (neuropathy) and usually follows a virus infection but can also be associated with immunizations, surgery, and childbirth. The cause is unknown but appears to be related to autoimmune reaction. Symptoms include weakness beginning in the legs and progressing upward, lost reflexes, and in severe cases, breathing can be affected. Patients can expect a slow but progressive recovery over several months maintaining vital functions and passively exercising the muscles. Plasmapheresis (removing toxic substances from the blood) has been shown to improve outcomes and shorten the disease as well as intravenous immunoglobulin.
Hyperthyroidism is an excess of thyroid hormone due to an overactive thyroid gland. Symptoms can include increased heart rate, weight loss, heart palpitations, frequent bowel movements, depression, fatigue, fine or brittle hair, sleep problems, thinning skin, and irregular vaginal bleeding. Graves' disease is the most common cause of hyperthyroidism. Many other health problems or taking excess thyroid hormone medication can cause an overactive thyroid gland. Treatment for the condition is with medication, radioactive iodine, thyroid surgery (rarely), or reducing the dose of thyroid hormone. No diet has been shown to treat hyperthyroidism or its symptoms and signs.
Is Lyme Disease Contagious?
Lyme disease may be transmitted to humans via the bite of an infected tick. The bacterium Borrelia burgdorferi causes the disease and is passed to humans during a tick's blood meal. Lyme disease does not spread from person to person.
Is MS Contagious? (Multiple Sclerosis)
Multiple sclerosis, or MS, is a degenerative disease of the covering around the nerves in the central nervous system (CNS). Researchers and doctors don't know the exact cause, but many theorize that it may be due to environmental triggers, an autoimmune disease, and viruses (infections). Symptoms of MS include vision changes, paralysis, vertigo, heat intolerance, slurred speech, sexual dysfunction, and urinary incontinence (the inability to urinate). There's no vaccine or cure for MS, but the progression and symptoms of the disease can be treated.
Migraine headache is a type of headache associated with a sensitivity to light, smells, or sounds, eye pain, severe pounding on one side of the head, and sometimes nausea and vomiting. The exact cause of migraine headaches is not known. Triggers for migraine headaches include certain foods, stress, hormonal changes, strong stimuli (loud noises), and oversleeping. Treatment guidelines for migraines include medicine, pain management, diet changes, avoiding foods that trigger migraines, staying hydrated, getting adequate sleep, and exercising regularly. Prevention of migraine triggers include getting regular exercise, drinking water daily, reducing stress, and avoiding trigger foods.
Multiple Sclerosis (MS)
Multiple sclerosis or MS is an autoimmune disorder in which brain and spinal cord nerve cells become demyelinated. This damage results in symptoms that may include numbness, weakness, vertigo, paralysis, and involuntary muscle contractions. Different forms of MS can follow variable courses from relatively benign to life-threatening. MS is treated with disease-modifying therapies. Some MS symptoms can be treated with medications.
Multiple Sclerosis (MS) Early Warning Signs and Types
Multiple sclerosis (MS) can be thought of as an immune-mediated inflammatory process involving different areas of the central nervous system (CNS) at various points in time. Early warning signs and symptoms of MS in children, teens, and adults are similar; however, children and teens with pediatric also may have seizures and a complete lack of energy. Adults with MS do not have these signs and symptoms. Other signs and symptoms of MS include inflammation of the optic nerve (optic neuritis), changes in vision, Wiping or having tissues around the eye and moving the eye may be painful, and double vision. There are four types of MS, relapsing remitting MS (RRMS), secondary progressive MS (SPMS), primary progressive MS (PPMS), and progressive relapsing MD (PRMS).
Myasthenia gravis, a chronic autoimmune neuromuscular disease. Varying degrees of weakness of the voluntary muscles of the body are the main characteristics. A defect in the transmission of nerve impulses of the muscles is the cause of myasthenia gravis. Myasthenic crisis is when the muscles that control breathing weaken, which requires immediate medical attention. Symptoms include weakness of the eye muscles, facial expression, and difficulty swallowing. Treatment of myasthenia gravis includes medical therapies to control the symptoms of the disease.
Periodic Paralysis Syndrome
Periodic paralysis syndrome comprises several types of rare muscle diseases in which a person experiences temporary muscle paralysis of one area of the body, or the entire body for a few minutes or days. The person regains normal muscle strength between periods of muscle weakness. You inherit the syndrome from your biological mother or father, or from a mutation in your genes. This gene mutation determines the type of periodic paralysis you have. The other symptoms depend upon the type of periodic paralysis you have.
A polio infection causes symptoms and signs such as paralysis, limb deformities, and even death. There is no curative treatment for polio. Treatment focuses on pain control, bed rest, and physical therapy.
Porphyria is a group of disorders that affect the nervous system, skin, or both. Porphyria is often an inherited condition that causes blistering, itching, and swelling of the skin. Treatment of porphyria may include avoiding triggers, receiving heme, taking medication, or having blood drawn to reduce iron levels in the body.
Postherpetic neuralgia (PHN) is a painful complication of shingles. Symptoms include severe pain, itchy skin, and possible weakness or paralysis of the area. There is no treatment for postherpetic neuralgia that is effective for all patients.
Progressive Supranuclear Palsy
Progressive supranuclear palsy, or PSP, is a rare neurodegenerative disease that is often misdiagnosed as Parkinson's disease because it carries similar symptoms. Because of its rarity, PSP is mostly unknown by the general public.
Snakebite (Snake Bite)
There are venomous (poisonous) and nonvenomous (nonpoisonous) snakes. A venomous snakebite penetrates the skin and injects, secretes, or spits a toxin into the penetrated wound. Symptoms of a venomous snakebite include redness at the site of the bite, swelling at the site of the bite, severe pain at the site of the bite, nausea and vomiting labored breathing disturbed vision increased sweating and salivation, and numbness or tingling in the face or arms and legs. Treatment of a venomous snake is a medical emergency, and the person that has been bitten needs to be taken to an emergency department or other emergent care facility as soon as possible.
Spina Bifida (Anencephaly, Neural Tube Defects) in Babies and Adults
Spina bifida is the most common neural tube defect in the United States. There are four types of spina bifida; 1) occulta, 2) closed neural tube defects, 3) meningocele, and 4) myelomeningocele. The cause of spina bifida is not known. Theories include genetic, nutritional, and environmental factors. Lack of folic acid during pregnancy is highly suspected. Symptoms of spina bifida vary from individual to individual. Treatment depends on the type of spanina bifida the person suffers.
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking, or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
Ticks are known transmitters of disease to humans and animals. Tick-borne diseases include Lyme disease, Rocky Mountain spotted fever, Q fever, tularemia, babesiosis, and Southern tick-associated rash illness. Infected ticks spread disease once they've bitten a host, allowing the pathogens in their saliva and mouth get into the host's skin and blood. Tick bites are typically painless, but the site of the bite may later itch, burn, turn red, and feel painful. Individuals allergic to tick bites may develop a rash, swelling, shortness of breath, numbness, or paralysis. Tick bite treatment involves cleaning and applying antibiotic cream.
West Nile Virus
West Nile virus (West Nile encephalitis) is a brain infection caused by a virus. People become infected with the virus after they're bitten by a mosquito that has fed off of a bird that's infected with the West Nile virus. Symptoms in humans include fever, headache, rash, body ache, and swollen lymph nodes. Treatment for a West Nile virus infection involves supportive care.
