From UPSC perspective, the following things are important :
Prelims level: MND and its causes; NIMHANS.
Why in the News?
The annual conference on Motor Neuron Disease (MND) ‘Awareness, Care and Management’ was held at NIMHANS.
What is Motor Neuron Disease (MND)?
- MND is a condition that affects the nerves in the brain and spinal cord, which are responsible for controlling your muscles.
- Over time, these nerves (called motor neurons) stop working properly, leading to muscle weakness and wasting away.
Types of MND:
- Amyotrophic Lateral Sclerosis (ALS): The most common type. It affects both upper and lower motor neurons, leading to weakness in various body parts.
- Progressive Bulbar Palsy (PBP): Affects the nerves in the brainstem, leading to problems with speaking and swallowing.
- Progressive Muscular Atrophy (PMA): Affects only the lower motor neurons, causing muscle weakness and wasting.
- Primary Lateral Sclerosis (PLS): Affects only the upper motor neurons, causing stiffness and movement difficulties.
Causes of MND:
- Genetic Factors: In some families, MND can be inherited due to specific gene mutations.
- Environmental Factors: Exposure to certain toxins, viruses, or physical injuries might contribute, but this is less clear.
- Age and Gender: It usually affects people between the ages of 50 and 70 and is slightly more common in men.
Symptoms:
- Muscle Weakness: Starts in one part of the body, like an arm or leg, and gradually spreads.
- Muscle Cramps and Twitching: Small, involuntary muscle movements.
- Difficulty Speaking and Swallowing: Due to weakness in the muscles used for these functions.
- Breathing Problems: In advanced stages, muscles that control breathing can be affected.
- Emotional Changes: Some people might experience changes in behavior or thinking.
Diagnosis:
- Clinical Examination: A doctor examines your symptoms and medical history.
- Electromyography (EMG): Tests the electrical activity of your muscles.
- Nerve Conduction Studies (NCS): Checks how well your nerves send signals.
- MRI: Scans to rule out other conditions.
- Genetic Testing: To check for inherited forms of MND.
Treatment:
There is no cure for MND, but treatments can help manage symptoms and improve quality of life.
- Medications:
- Riluzole: Can slow down the progression of ALS.
- Edaravone: Another drug that may slow down the decline in daily activities.
- Symptomatic Treatments: For muscle cramps, excess saliva, and emotional symptoms.
- Therapies:
- Physical Therapy: Helps maintain muscle strength and mobility.
- Occupational Therapy: Aids in performing daily activities.
- Speech Therapy: Assists with speech and swallowing difficulties.
- Respiratory Therapy: Supports breathing issues.
