Parkinson’s disease is a progressive brain condition that most Pakistani families associate with shaking hands in an elderly relative. That image is not wrong, but it is incomplete. The shaking, known as a resting tremor, is rarely the first thing that goes wrong.
Researchers now know that the brain changes underlying Parkinson’s can begin a decade or more before any movement problem appears. According to the World Health Organization, over 8.5 million people were living with Parkinson’s disease globally as of 2019, and that number is rising faster than for any other neurological disorder. According to the Pakistan Parkinson’s Society, an estimated 450,000 Pakistanis are affected by the condition, and a 2024 systematic review published in the Pakistan BioMedical Journal confirmed that reported cases in Pakistan have increased steadily over the last decade, with males more commonly diagnosed than females.
Recognising the earlier, subtler signals matters because timely neurological evaluation can guide better management. The sections below walk through those signals clearly.
پارکنسن کی بیماری: اہم باتیں
پارکنسن کی بیماری ایک دماغی عارضہ ہے جو حرکت کو متاثر کرتا ہے اور اس کی ابتدائی علامات اکثر کانپنے سے بہت پہلے ظاہر ہوتی ہیں۔ پاکستان میں ایک اندازے کے مطابق چار لاکھ پچاس ہزار افراد اس مرض میں مبتلا ہیں۔ ابتدائی علامات میں سونگھنے کی صلاحیت میں کمی، نیند کے دوران بے قراری، قبض، اور لکھائی کا چھوٹا ہو جانا شامل ہیں۔ ان علامات کو عمر کا تقاضہ سمجھ کر نظرانداز نہ کریں، بلکہ کسی ماہر نیورولوجسٹ سے مشورہ کریں۔
What Are the Early Warning Signs of Parkinson’s Disease?
The early warning signs of Parkinson’s disease fall into two broad groups: non-motor symptoms (which have nothing to do with movement) and motor symptoms (which involve how the body moves). Non-motor signs can appear years, sometimes a decade, before any tremor develops.
A 2019 study published in the European Journal of Neurology found that over 90% of patients with newly diagnosed Parkinson’s disease reported experiencing at least one non-motor symptom before their movement problems began. These pre-diagnosis signals are called prodromal features, meaning they precede the full clinical picture.
Here are the nine most clinically recognised early signals:
- Loss of smell (anosmia): A reduced or absent ability to detect odours affects up to 90% of Parkinson’s patients and can appear years before motor symptoms, according to research cited by the National Institutes of Health. Many Pakistani patients attribute this to chronic sinusitis or allergies and never connect it to a neurological cause.
- Constipation: Persistent, new-onset constipation, not explained by diet or medication, may reflect early changes in the gut’s nervous system. The enteric nervous system is one of the first areas affected in Parkinson’s pathology.
- REM sleep behaviour disorder: Acting out dreams physically, kicking, shouting, or punching during sleep, is a recognised prodromal marker. Family members in the same bed are usually the first to notice.
- Resting tremor: A slow, rhythmic shaking of a hand, finger, or chin that occurs when the limb is completely relaxed and stops when the person reaches for something. This is distinct from the tremor of anxiety or essential tremor.
- Bradykinesia (slowness of movement): Tasks that once felt automatic, buttoning a shirt, rising from a chair, turning in bed, begin to take noticeably longer. This slowness is one of the three cardinal motor features neurologists look for.
- Muscle rigidity: Stiffness in the arms, legs, or shoulders that does not ease with gentle stretching. Some patients describe a feeling of lead in the limbs.
- Micrographia (small handwriting): Letters become progressively smaller and more crowded across a line of text. This is one of the earliest motor signs and is easy to test at home by asking someone to write a sentence.
- Soft or monotone voice: The voice loses its natural volume and expressiveness. Family members may repeatedly ask the person to speak up.
- Masked face (hypomimia): A reduction in spontaneous facial expression, making the person appear blank or uninterested even during pleasant conversation.
A Critical Point for Pakistani Patients: It May Not Start with a Tremor
Most Pakistani families wait for visible shaking before considering a neurological assessment. This wait can cost years of earlier management.
A study on Parkinson’s disease in South Asian populations, published in a peer-reviewed epidemiological review, found that South Asians, including Pakistanis, are more prone to a rigid-akinetic dominant phenotype of the disease. This means the dominant early feature is slowness of movement and muscle stiffness, not a tremor. A Pakistani patient may be significantly affected for months before any shaking appears. Research from the Aga Khan University Hospital in Karachi further documented that rigidity and bradykinesia, along with difficulty performing fine motor tasks, were among the most common presenting features in Pakistani patients.
Additionally, a cross-sectional study on non-motor symptoms in Pakistani Parkinson’s patients, published in BMJ Open in 2018, noted a higher frequency of non-motor symptoms in the Pakistani population compared to data from other populations. This means the gut symptoms, sleep disruption, and mood changes deserve particular attention in Pakistani patients, not just the movement signs.
Motor vs Non-Motor Signs: A Quick Comparison
| Feature | Motor Signs | Non-Motor Signs |
|---|---|---|
| When they appear | Later in disease course | Can appear years before motor signs |
| Examples | Tremor, rigidity, slow movement | Loss of smell, constipation, REM sleep disorder |
| Visibility | Visible to others | Often invisible, internal |
| Commonly mistaken for | Arthritis, essential tremor, aging | Aging, IBS, depression, sinusitis |
| Diagnostic weight | Required for clinical diagnosis | Support diagnosis, not sufficient alone |
Mood Changes and Sleep Problems as Early Signals
Depression and anxiety are not only emotional responses to a difficult diagnosis. In many cases, they precede the diagnosis by years. Parkinson’s affects dopamine pathways that regulate mood as well as movement, so low mood, persistent fatigue, and unexplained anxiety can be early neurological features rather than purely psychological ones.
Sleep disruption beyond REM behaviour disorder is also common. Patients report difficulty staying asleep, restless legs, and excessive daytime sleepiness. In Pakistan, where disturbed sleep in older adults is frequently attributed to stress or prayer schedules, these symptoms rarely prompt a neurological referral.
Do You Need to See a Specialist? A Simple Self-Check
If you or a family member has noticed three or more of the following, a consultation with a neurologist in Pakistan is worth arranging:
- Persistent loss of smell with no cold or sinus infection to explain it
- New-onset constipation lasting more than a few weeks
- Physically acting out dreams during sleep
- Handwriting that has become noticeably smaller
- One hand or arm that trembles at rest
- Movements that feel slower than they used to
- A voice that family members say has become quieter
- Stiffness in the shoulders or arms that does not improve
- A face that others describe as expressionless
If 3 or more of these apply, consider arranging a neurological evaluation. These signs do not confirm Parkinson’s disease, but they warrant professional assessment.
For context on how early detection works with other progressive conditions, the approach mirrors what is recommended for diabetes symptoms in Pakistan, where acting on subtle signals before the obvious ones appear makes a meaningful difference to long-term outcomes.
How Is Parkinson’s Disease Diagnosed in Pakistan?
There is no single blood test or scan that confirms Parkinson’s disease. Diagnosis is clinical, meaning a neurologist evaluates the pattern and combination of symptoms in person. According to neurologists at Mass General Brigham, providers typically look for at least two of three cardinal signs: resting tremor on one side of the body, slowness of movement on one side, and muscle rigidity.
In Pakistan, access to movement disorder specialists is concentrated in larger cities. Lahore, Karachi, and Islamabad have the highest density of neurologists with experience in Parkinson’s. Patients in smaller cities or rural areas can face delays of several years between symptom onset and a confirmed diagnosis, which underscores the value of early awareness.
A DaTscan (dopamine transporter scan) can support diagnosis in uncertain cases, though availability in Pakistan is limited and cost is a practical barrier for many families.
Get Expert Help from Marham
Getting to the right specialist quickly is not always straightforward in Pakistan, particularly when the presenting symptoms are non-motor and easy to dismiss as aging or stress. A neurologist who understands movement disorders can take a full history, examine the subtle motor signs that are not obvious to a non-specialist, and decide whether further investigation is needed.
Marham connects Pakistani patients with verified neurologists in Pakistan through both in-person and online consultations, so geography does not have to be a barrier to a proper assessment. A consultation typically takes 20 to 30 minutes and gives you a clear picture of whether the symptoms you have noticed are worth investigating further, and what the next steps would look like.
Frequently Asked Questions
What is usually the very first sign of Parkinson’s disease?
For many patients, the first sign is a non-motor one: loss of smell, persistent constipation, or acting out dreams during sleep. These can appear years before any movement problem. A resting tremor, though the most recognised sign, is not always the first.
Can Parkinson’s disease symptoms come and go in the early stages?
Early non-motor symptoms such as constipation, sleep disruption, and mood changes can fluctuate. Motor symptoms, once they appear, tend to be more consistent and progressive. Fluctuation does not rule out Parkinson’s and should still be evaluated by a neurologist.
At what age does Parkinson’s disease usually begin in Pakistan?
A clinical study from the Aga Khan University Hospital in Karachi found a mean age of onset of 54 years in Pakistani patients, with most cases presenting in the sixth or seventh decade of life. Early-onset Parkinson’s, before age 50, accounts for roughly 5 to 10% of cases globally, according to the National Institute on Aging.
Is Parkinson’s disease more common in men or women in Pakistan?
Yes, males are more commonly diagnosed. The 2024 Pakistan BioMedical Journal systematic review and the Aga Khan University Hospital study both found that men make up roughly 60 to 63% of diagnosed Parkinson’s cases in Pakistan, consistent with the global pattern.
Can early Parkinson’s disease be confirmed with a blood test?
No. There is currently no blood test that diagnoses Parkinson’s disease. Diagnosis requires a clinical evaluation by a neurologist, based on the pattern of motor and non-motor symptoms. Research into biomarkers is ongoing, but no such test is in routine clinical use in Pakistan.
Conclusion
The early warning signs of Parkinson’s disease are real, recognisable, and worth taking seriously long before a tremor appears. Loss of smell, disrupted sleep, persistent constipation, and gradually slowing movement are the body’s earliest signals of a change in the brain’s dopamine system. For Pakistani patients, the picture is complicated further by a tendency toward stiffness and slowness rather than obvious shaking as the dominant early feature. Noticing these signs and seeking a neurological opinion early gives the best foundation for managing the condition well over the long term.
