Which disease affects nerve cells and leads to death?
ALS affects the nerve cells that control voluntary muscle movements such as walking and talking (motor neurons). ALS causes the motor neurons to gradually deteriorate, and then die.
What causes nerve cell death?
Later in life, inappropriate neuronal cell death may result from pathological causes such as traumatic injury, environmental toxins, cardiovascular disorders, infectious agents, or genetic diseases. In some cases, the death occurs through apoptosis.
What diseases are caused by apoptosis?
Neurodegenerative diseases, such as Alzheimer’s disease, Huntington’s disease, and Parkinson’s disease are all characterized by excessive apoptosis of neurons. For example, Alzheimer’s disease is caused by accumulation of b-amyloids at lesion sites where b-amyloids induce abnormal apoptosis of neurons.
What disease affects nerve cells?
Examples include:
- Parkinson’s disease.
- Multiple sclerosis (MS).
- Amyotrophic lateral sclerosis (ALS).
- Alzheimer’s disease.
- Huntington’s disease.
- Peripheral neuropathies.
Which genetic disease causes the death of neurons?
Tay-Sachs disease is a rare, inherited disorder that is characterized by neurological problems caused by the death of nerve cells (neurons ) in the brain and spinal cord (central nervous system). The most common form of Tay-Sachs disease, known as infantile Tay-Sachs disease, becomes apparent early in life.
Is ALS a demyelinating disease?
ALS, mainly consisting of progressive axonal degeneration, might show temporal demyelinating features of peripheral nerves both electrophysiologically and pathologically. The pathomechanism for the demyelination in ALS remains to be elucidated.
Why is the death of nerve cells very serious?
When these neurons die, people lose their capacity to remember and their ability to do everyday tasks. Physical damage to the brain and other parts of the central nervous system can also kill or disable neurons.
Why is neuron death important?
Neuronal cell death (apoptosis) plays an important role in normal neural development. When a muscle is first innervated, far more than the normal adult number of neurons supply it. Some axons fail to reach their normal target, and cell death is a way of eliminating them.
What are the diseases related to apoptosis and what is the mechanism?
Dysregulation of the controlling mechanisms of this system results in disease. Deficient apoptosis is associated with cancer, auto-immunity and viral infections. Excessive apoptosis is associated with ischaemic heart disease, stroke, neurodegenerative disease, sepsis and multiple organ dysfunction syndrome.
What are the disorders if there is too little cell death?
And when apoptosis malfunctions, the results may be dire: cancer and autoimmune diseases when there is too little apoptosis, and possibly stroke damage or the neurodegeneration of Alzheimer’s disease when there is too much.
What are the diseases and disorders of the nervous system?
Brain and nervous system problems are common. These neurological disorders include multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, epilepsy, and stroke, and can affect memory and ability to perform daily activities.
