Parkinson Disease

A brain disorder called Parkinson's disease causes stiffness, tremors, balance problems, and other accidental or unconscious movements.

Parkinson Disease

Usually, symptoms are minor to begin with and worsen over time. People may find it challenging to move about and speak as their condition develops. They might also have behavioural and mental changes, sleep problems, depression, memory loss, and weariness. Although practically everyone is at risk of developing Parkinson's, several studies show that men are more likely than women to have this disorder. Research is being done to identify any potential risk factors, even though the aetiology is unclear. Age clearly presents a risk. Parkinson's disease frequently initially appears in persons over the age of 60, even though 5% to 10% of patients show symptoms before the age of 50. Although not always, early-onset Parkinson's disease is typically inherited, and some forms have been connected to genetic variants.

What Triggers Parkinson's Illness?

The brain's basal ganglia, which controls movement, is where the nerve cells that cause Parkinson's disease's most obvious signs and symptoms are harmed or killed. Dopamine, a crucial neurotransmitter in the brain, is continuously produced by these nerve cells, or neurons. Movement issues are brought on by decreased dopamine synthesis due to neuronal degeneration or death. Researchers are still investigating the reasons of neuronal degeneration.

Parkinson's sufferers also experience a loss of norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many physiological activities like heart rate and blood pressure. a few Parkinson's sufferers Fatigue, fluctuating blood pressure, sluggish digestion, and a sharp drop in blood pressure when rising from a laying or sitting position are non-movement symptoms that may be caused by a lack of norepinephrine.

The many brain cells of Parkinson's disease patients have Lewy bodies, peculiar collections of the protein alpha-synuclein. Researchers are trying to understand how the genetic variations that affect diseases like Parkinson's and Lewy body dementia link to the pathogenic and normal roles of alpha-synuclein.

Some cases of the ailment appear to be inherited, and a small fraction of Parkinson's disease cases can be connected to specific genetic abnormalities. Parkinson's disease rarely runs in families, even though it is known to have a hereditary component. Many researchers now believe that Parkinson's disease is brought on by a confluence of hereditary and environmental variables, including exposure to toxins.


The indications and symptoms of Parkinson's disease vary from person to person. Early warning indications could be ignored or given little weight. The symptoms frequently begin on one side of the body and are most severe there, even after they start to affect the limbs on both sides. Parkinson's disease symptoms include-

  • Tremor- A limb, generally your hand or fingers, is where tremor, or rhythmic shaking, typically begins. You could move your thumb and forefinger. An expression for this is "pill-rolling tremor". Even when your hand is relaxed, it may quiver. Working on a task can help the shaking stop.
  • Bradykinesia- It is typified by slow movement. Parkinson's disease may ultimately cause movement to slow down, making routine tasks challenging and time-consuming. Your steps may get smaller as you move forward. It could be difficult to get out of a chair. When attempting to walk, you may shuffle or drag your feet.
  • Rigid Muscles- On the body, muscles can become stiff in any location. Your range of motion may be limited by stiff muscles, which can be uncomfortable.
  • Poor posture and balance- You could begin to sag. Additionally, Parkinson's disease may affect your balance or make you trip.
  • A decrease in automatic movement- It might be more difficult for you to move your arms, smile, blink, or blink without meaning to.
  • Alterations in speech- You can stutter, speak quickly or softly, or hesitate before you speak. It's possible that you speak more monotonously and without the typical speech rhythms.


Neurons are a type of nerve cell that eventually degrade or die because of Parkinson's disease. The loss of neurons in your brain that create the chemical messenger dopamine is the primary cause of many Parkinson's symptoms. Dopamine shortage leads to abnormal brain activity, which exacerbates movement issues and other Parkinson's disease symptoms.

Although there is no known cause of Parkinson's disease, several factors, such as:

  • Genes- Scientists have identified the precise genetic alterations that might cause Parkinson's disease. They are not likely, though, unless other family members also suffer from Parkinson's disease. Each of these genetic indicators has a relatively modest risk of Parkinson's disease, despite the fact that some gene alterations do seem to raise the incidence of the illness.
  • Environmental triggers- The risk of developing Parkinson's disease after exposure to certain chemicals or environmental factors is exceedingly low.

Researchers have also found that persons with Parkinson's disease have a wide range of abnormalities in their brains, albeit it is yet unknown why these alterations occur. These alterations consist of: -

  • Lewy bodies- Lewy bodies are one illustration of this. Clusters of certain substances within brain cells are one of the disease's microscopic symptoms. Because of what they are, Lewy bodies are thought to be crucial to understanding the mechanisms causing Parkinson's disease.
  • Alpha-synuclein is seen in Lewy bodies- Alpha-synuclein, often known as a-synuclein, is a protein that is widely distributed in nature and is assumed to be a key component of Lewy bodies. Because cells cannot break it down, it is clumped in all Lewy bodies. This is a topic that researchers studying Parkinson's disease are currently concentrating on a lot. Studies have shown that alpha-synuclein protein clumps in the spinal fluid of persons who subsequently develop Parkinson's disease.

Risk Component

It includes-

  • Age- Age is one of the risk factors for Parkinson's disease. Parkinson's disease rarely develops in young adults. As you get older, your risk of acquiring it rises because it often manifests in middle or later life. People with the illness are often 60 years of age or older. Genetic counselling may be useful to help with family planning decisions if a young person is diagnosed with Parkinson's disease. Additional aspects that differ from those of a younger individual with Parkinson's disease and call for special care include work, social circumstances, and drug side effects.
  • Heredity- Your likelihood of contracting Parkinson's disease increases if you have close relatives who have the disorder. Your risks are still quite minimal unless you have a sizable number of family members who are affected with Parkinson's disease.
  • Sex- Men are more frequently affected by Parkinson's disease than women are.
  • The effects of Toxins- Regular exposure to pesticides and herbicides may modestly raise your risk of developing Parkinson's disease.


These additional problems, which Parkinson's disease patients regularly experience and might be controllable:

  • Problems with cognition- You can be dealing with cognitive and mental issues, like dementia. These frequently manifest in Parkinson's disease's later stages. In most cases, medication doesn't help with certain cognitive issues.
  • Emotional alterations and depression- Depression can have an impact on you even in its very early stages. If depression is controlled, it might be simpler to handle the added difficulties of Parkinson's disease. Additional emotional changes like fear, concern, or a lack of motivation could also occur. You might be given medication by your medical team to treat these symptoms.
  • Swallowing issues- When your health deteriorates, you can start having trouble swallowing. If you swallow slowly, saliva may accumulate in your mouth, which could cause you to drool.
  • Issues chewing and eating- In the later stages of Parkinson's disease, mouth muscles are affected, which makes chewing challenging. This could lead to choking and poor nutrition.
  • Problems and difficulties sleeping- Parkinson's disease patients frequently have sleep problems, including frequent nocturnal awakenings, early morning awakenings, or daytime sleepiness. You might sleep better if you take medication.
  • Bladder problems- Parkinson's disease can cause bladder problems, such as an inability to control pee or problems urinating.
  • Constipation- Parkinson's disease frequently manifests as constipation, which is primarily caused by a slow-acting digestive system.
  • Blood pressure- Blood pressure changes are one potential result. You may have dizziness or faintness if your blood pressure quickly decreases when you stand up (orthostatic hypotension).
  • Disruptive odours- You may not have a functioning sense of smell. Some scents can be challenging to identify or differentiate from one another.
  • Fatigue- Parkinson's disease patients frequently feel worn out and under the weather, especially later in the day. There are times when no cause is known.
  • Pain- Parkinson's disease patients occasionally feel pain, either locally or more widely throughout their body.
  • Poor sexual maturation- Some Parkinson's disease patients assert that their arousal or performance during sexual activity has declined.


There is no known technique to prevent Parkinson's because there is no known cause for it. Regular aerobic exercise may reduce the risk of acquiring Parkinson's disease, according to numerous research.

Another study found a link between caffeine and a lower prevalence of Parkinson's disease. Caffeine is found in coffee, tea, and cola. Additionally, Parkinson's disease is regarded to be less likely to occur in green tea consumers. Currently, there is no established link between caffeine and any disease, including Parkinson's. There is currently no proof that consuming coffee or other caffeinated drinks will fend off Parkinson's.
