Parkinson’s disease

What is Parkinson's disease?

Parkinson’s occurs when nerve cells in the substantia nigra stop producing enough dopamine, the chemical messenger responsible for smooth, coordinated movement. As dopamine levels drop, movement becomes slower, stiffer, and harder to control.

The disease's hallmark is a buildup of Lewy bodies, protein deposits in the brain. This process starts years, sometimes decades, before tremors appear, often affecting sleep, mood, and digestion first.

Because Parkinson’s exists on a broad spectrum, symptoms and how fast they progress vary a lot from person to person. It's not immediately life-threatening, but catching these shifts early matters for maintaining mobility, energy, and quality of life over the long run.

Parkinson's symptoms are divided into motor and non-motor categories. Non-motor symptoms frequently appear first and are often overlooked or attributed to other causes.

Non-motor symptoms:

• Loss of smell (hyposmia or anosmia)

• REM sleep behaviour disorder (physically acting out vivid dreams)

• Constipation

• Depression and anxiety

• Fatigue and cognitive slowing

• Orthostatic hypotension (dizziness on standing from autonomic dysfunction)

Motor symptoms:

• Resting tremor, typically beginning in one hand

• Bradykinesia (slowness of movement) such as reduced arm swing, shuffling gait

• Muscle rigidity, stiffness throughout the range of motion

• Postural instability, balance difficulties, increasing fall risk

• Small handwriting (micrographia) and reduced facial expression (hypomimia)

• Softened or monotone speech

Symptoms typically start on one side of the body and gradually spread to both sides over time.

The exact cause of Parkinson’s disease isn’t fully understood, but several factors seem to play a role:

• Genetic predisposition: Certain inherited changes can slightly increase risk.

• Age: Most cases appear after age 60, though early-onset Parkinson’s can occur earlier.

• Environmental exposure: Long-term contact with certain chemicals or toxins may contribute.

Parkinson’s is a clinical diagnosis, meaning no single test confirms it. However, diagnostics are essential to rule out "Parkinsonisms", conditions that mimic its symptoms but require different treatments.

Brain MRI: MRI cannot diagnose Parkinson's directly, but it is essential for ruling out structural mimics like normal pressure hydrocephalus (fluid buildup), vascular parkinsonism (small strokes), or brain tumors. It also helps identify atypical syndromes like multiple system atrophy.

Elfcare's full body MRI includes detailed brain imaging as standard, so it is directly relevant to identifying or excluding these structural mimics.

Blood tests cannot detect Parkinson's but identify metabolic contributors and rule out conditions causing similar symptoms. Relevant markers in Elfcare's panel include:

• Vitamin B12 & Folate: A deficiency can cause tremors and cognitive slowing that mimic or worsen neurological decline.

• Homocysteine: High levels are linked to accelerated brain aging and neurodegeneration.

• Thyroid Panel (TSH/T3/T4): Thyroid dysfunction often causes stiffness and tremors that appear parkinsonian.

• Ferritin: Abnormal levels, whether high or low, can point to the iron-related oxidative stress processes implicated in Parkinson's.

• CRP: A marker of systemic inflammation; neuroinflammation is increasingly recognized as a contributor to how Parkinson's progresses.

• HbA1c & Glucose: Metabolic health is closely linked to the risk and speed of neurological decline.

Why early detection matters

The neurodegeneration behind Parkinson's begins years before motor symptoms appear. While there is currently no treatment that stops this process, early identification of structural mimics allows for treatment of reversible conditions.

Catching metabolic risk factors early, things like B12 deficiency, thyroid dysfunction, or elevated homocysteine, means they can be corrected in ways that support neurological health. And an early referral to a specialist, when Parkinson's is clinically suspected, means treatment can start sooner, which meaningfully improves quality of life and independence for longer.

How Elfcare can help

Elfcare focuses on early detection and empowerment. Our approach identifies the structural and metabolic factors that influence brain health, helping you distinguish between primary neurological conditions and treatable imbalances.

Elfcare's brain MRI can identify structural causes of parkinsonian symptoms, including normal pressure hydrocephalus, vascular changes, and other conditions that are treatable and must be excluded before a Parkinson's diagnosis is considered.

Our blood panel rules out metabolic mimics such as thyroid dysfunction, B12 deficiency, and elevated homocysteine and identifies the systemic factors most closely linked to neurological vulnerability.

Elfcare cannot diagnose Parkinson’s disease; that requires a specialist neurological assessment. However, if our tests turn up a structural or metabolic irregularity, we'll arrange follow-up diagnostics and refer you to a specialist so you get the right care early.
