There are many causes of tremors, which is an unintentional and uncontrollable rhythmic movement of one part or one limb of your body.
It does not always signify Parkinson’s disease.
While the hands may be the most noticeable part of the body to have a tremor, this symptom does not always have to occur in your hands.
It can occur in any part of the body and at any time.
However, it is important not to confuse muscle spasms and twitches with tremors.
A muscle spasm is an involuntary contraction of your muscle.
A muscle twitch is an uncontrolled fine movement of a small portion of a larger muscle.
Are you sure your friend is having a tremor and not a muscle spasm or twitch?
Well then, there are two types of tremors: resting and action.
Resting tremors are when you’re sitting or lying still.
Once you move around, the tremor actually goes away.
Resting tremors often affect only your hands or fingers.
Action tremors occur when you move the affected body part.
Action tremors are further divided into:
- Intention tremor
This happens during an intentional movement, such as touching your finger to the elevator button.
- Postural tremor
This occurs when holding a position against gravity, such as holding out your arms or legs.
- Task-specific tremors
This happens during a specific activity, such as typing on your keyboard or writing with your pen.
- Kinetic tremors
This occurs during movement of a body part, such as moving your wrist up and down.
- Isometric tremors
This happens during the voluntary contraction of a muscle without moving it.
A Parkinson’s tremor is a resting tremor, and it occurs early in the disease.
Tremors can be caused by many things.
Some of them are mild, and you need not worry too much about them.
Some are quite serious.
Causes of tremors include:
- Muscle fatigue
- Drinking too much coffee
- Too much stress
- Stroke or some brain injury that affects the cerebellum – the part of your brain that controls movement and balance
- Multiple sclerosis affecting the cerebellum
Parkinson’s disease is a brain disorder that causes some uncontrollable movements, such as tremors, shaking, stiffness, and difficulty with balance and coordination.
Most people develop it after the age of 60.
It occurs more often in men than women.
Parkinson’s disease happens because the nerve cells in your basal ganglia, which is in an area of your brain that controls movement, are impaired or dead.
Therefore, they produce less dopamine.
To this day, no one knows why the cells in the basal ganglia just die like that.
Symptoms usually begin gradually and worsen over time.
After a while, many people have difficulty with walking and talking.
They may also develop mental and behavioural changes, sleep problems, depression, memory difficulties and fatigue.
Here are 10 signs that might indicate you have early Parkinson’s disease.
If you have just one of these signs, it is OK – you need not worry so much.
But if you have two or more of these signs, then you should consult a neurologist.
- Tremor at rest
- Small handwriting (compared to your usual handwriting)
- Loss of smell, especially for bananas
- Sudden movements during sleeping (usually noticed by your spouse)
- Stiffness in moving or walking, especially stiffness that does not go away when you move.
- Change of voice to soft or low
- An expressionless or mask-like face
- Dizziness or fainting
- Stooping or hunching
There is no cure, but there are medications containing levodopa that will help alleviate the symptoms.
They can be ingested, inhaled or infused.
There are also many other types of drugs that can be used to help treat Parkinson’s disease, along with levodopa.
