Beyond tremors four early signs of Parkinson’s you must know

Parkinson’s disease is often associated with tremors, but experts warn there are several early warning signs that can appear long before noticeable movement issues. Affecting more than 166,000 people in the UK, the degenerative neurological condition is caused by the loss of dopamine-producing nerve cells in the brain, which coordinate movement.

While tremors are familiar, up to 20 per cent of patients may never develop them. Instead, non-motor symptoms can emerge years before classic motor signs. One of the earliest indicators is a loss of sense of smell. Around 95 per cent of Parkinson’s patients experience reduced or absent smell, sometimes up to 20 years before diagnosis. This subtle change can affect appetite, mood, and even safety, as sufferers may be unable to detect smoke or gas.

Another early symptom is acting out dreams during REM sleep. Normally, the body is paralyzed in this sleep stage, but patients with REM sleep behaviour disorder may thrash, talk, or sit up during dreams. Studies show 50–70 per cent of those with this disorder eventually develop Parkinson’s or related conditions within 5–10 years.

Constipation is another common early sign. Parkinson’s can affect nerves in the gut and slow bowel muscles, causing chronic constipation. Research suggests those with persistent constipation have twice the risk of developing Parkinson’s later in life.

Finally, dizziness when standing, known as orthostatic hypotension, can signal neurological issues that may precede Parkinson’s. Studies show that around 23 per cent of patients with unexplained dizziness develop Parkinson’s or related conditions over a decade.

While not everyone with these symptoms will develop the disease, early recognition is crucial. Detecting Parkinson’s early allows for interventions that can significantly improve quality of life, even decades before movement difficulties arise. Experts stress awareness of subtle signs can be just as important as spotting tremors.
