Question

What are the main degenerative diseases of the nervous system?

Answer 1

Degenerative nerve diseases have an effect on various of your body's activities, like balance, movement, talking, breathing, and heart function. Several of these diseases are genetic. Occasionally the reason is a medical condition like alcoholism, a tumor, or a stroke. Further causes may well include toxins, chemicals, and viruses. At times the cause is not known.

Degenerative nerve diseases include following

Alzheimer's disease (AD) is the most widespread form of dementia amongst older people. Dementia is a brain disorder which gravely affects a person's capability to carry out every day activities.

AD begins little by little. Initially it involves the parts of the brain which have power over thought, memory as well as language. Individuals with AD may have difficulty recollection things that happened in recent times or names of people they know. A associated problem, mild cognitive impairment (MCI), causes added memory problems than usual for people of the same age. Several, but not all having MCI will develop AD.

In AD, over time, symptoms get bad. Ultimately, they need full care.

AD generally begins after age 60. The threat goes up as you get older. Your hazard is also higher if a family member has had the disease.

No cure can stop the disease. Though, a number of drugs may assist keep symptoms from getting worse for a restricted time.

Amyotrophic lateral sclerosis (ALS) is a nervous system disorder which attacks nerve cells known as neurons in your brain as well as spinal cord. These neurons pass on messages from your brain and spinal cord to your voluntary muscles in your arms and legs etc. At earliest, this causes meek muscle problems. A number of people notice

walking or running , writing trouble andSpeech problems

Ultimately, you lose your vigor and cannot move. When muscles in your chest stop working, you cannot breathe. A breathing machine can help out, however the majority of the people with ALS die from respiratory failure.

The disease typically strikes between age 40 and 60. It is more in men than women. No one knows what leads to ALS. There is no cure for it. Medicines can ease symptoms and, occasionally, extend survival.

Friedreich's ataxia is an hereditary disease which damages your nervous system. The damage affects your spinal cord as well as the nerves which manage muscle movement in your arms and legs. Symptoms generally begin between the ages of 5 and 15. The foremost symptom is ataxia, that is trouble coordinating movements. Particular symptoms include

• Difficulty in walking
• Weakness in Muscles and Speech problems
• Involuntary movements in eyes
• Scoliosis
• Heart palpitations
• People with Friedreich's ataxia typically need a wheelchair 15 to 20 years following symptoms first become visible. In severe cases, people turn out to be incapacitated. There is no cure for it. Treatment of symptoms is done by medicines, braces, surgery, and physical therapy.

Huntington's disease (HD) is an hereditary disease which causes definite nerve cells in the brain to waste away. People are born with the malfunctioning gene, however symptoms generally don't become visible until middle age. Near the beginning symptoms of HD may comprise of hysterical movements, clumsiness, as well as balance problems. Later on, HD can take away the capability to walk, talk, and swallow. A number of people stop recognizing family members. If one of your parents has Huntington's disease, you have a 50 percent chance of getting it. A blood test can tell you if have the HD gene and will develop the disease. Genetic counseling can help you weigh the risks and benefits of taking the test.

There is no cure for it. Medicines can assist control a number of of the symptoms, although cannot slow down or stop the disease.

Lewy body disease is one of the most universal causes of dementia in the aged people. Dementia is the failure of mental functions severe enough to influence normal actions and relations. Lewy body disease happens at what time of abnormal structures, called Lewy bodies, build up in parts of the brain. The disease may cause a extensive variety of symptoms, including

• Aalertness and attention changes
• Hallucinations and troubles with movement and posture
• Muscle stiffness, Confusion and Loss of memory

.

Lewy body disease generally begins between the ages of 50 and 85. The disease gets bad over time having no cure. Treatment focuses on drugs to aid symptoms.

Parkinson's disease (PD) is a kind of movement disorder. It happens as nerve cells in the brain don't manufacture adequate of a brain chemical called dopamine. Occasionally it is genetic, however most cases do not appear to run in families. Contact to chemicals in the environment may play a role.

Symptoms begin slowly, habitually on one side of the body. Afterward they affect both sides, whichinclude

• Trembling of hands, arms, legs, jaw as well as face
• Stiffness of the arms, legs and trunk along with Slowness of movement
• Poor balance and poor coordination

As symptoms get bad, people with the disease might have trouble walking, talking, or doing easy tasks. They may also have troubles like depression, sleep problems, or trouble chewing, swallowing, or speaking.

PD typically begins around age 60, however it can start earlier. It is more widespread in men than in women. There is no cure for PD but a range of medicines occasionally help symptoms considerably.

Spinal muscular atrophy (SMA) is a inherited disease which attacks nerve cells, known as motor neurons, in the spinal cord. These cells correspond with your voluntary muscles - the ones you can have power over, like in your arms and legs. But as the neurons die, the muscles grow weaker, thus can affect walking, crawling, breathing, swallowing, and head and neck control.
