Neurodegenerative diseases are a group of disorders characterized by the progressive degeneration or death of nerve cells (neurons) in the brain and spinal cord. This leads to problems with movement (motor function), cognition (thinking and memory), and sometimes behavior or emotions. These diseases are usually chronic, progressive, and currently incurable, although some treatments can slow progression or manage symptoms.
Genetic problems – Sometimes a disease is passed from parents to children through genes (like Huntington’s disease).
Abnormal protein build-up – Sometimes harmful proteins collect in the brain and damage nerve cells.
Low energy in brain cells – Brain cells need energy to work. If they don’t produce enough energy, they can become weak and die.
Oxidative stress – Harmful molecules (called free radicals) can damage brain cells over time.
Long-term inflammation – If the brain stays inflamed for a long time, it can slowly damage nerve cells.
Environmental factors – Things like toxins, head injuries, or unhealthy lifestyle habits may increase the risk.
Neurodegenerative diseases are conditions in which brain cells slowly become damaged and die over time. They may be caused by genetic factors, changes inside the body, or environmental influences. Although there is no complete cure yet, early diagnosis and proper treatment can help improve quality of life. Research is ongoing to develop therapies that can slow or stop disease progression.
