Parkinson’s Disease Treatment in Istanbul

What is Parkinson’s disease?

Parkinson’s disease is a progressive neurodegenerative condition that occurs when the nerve cells producing dopamine in a small area of the brain — the substantia nigra — break down and die. Dopamine carries the signals that make movement smooth and automatic. As it falls, movement becomes slower, smaller and harder to start.

By the time the first visible symptoms appear, a substantial proportion of those cells have already been lost. This is why the condition is often present for years before diagnosis, and why the useful question is rarely “can it be stopped” but “how well can it be managed, and for how long”.

Parkinson’s disease is not the same as parkinsonism. Several other conditions — multiple system atrophy, progressive supranuclear palsy, drug-induced parkinsonism — produce similar symptoms but respond very differently to treatment. Telling them apart is one of the most consequential parts of assessment, because the surgical options that help Parkinson’s disease do not help atypical parkinsonism.

Symptoms and how they progress

No two patients follow the same path, but the motor picture is recognisable.

Tremor is the symptom most people associate with Parkinson’s, but it is usually the slowness and rigidity that determine how much of daily life the condition takes. A significant minority of patients never develop prominent tremor at all.

Non-motor symptoms deserve more attention than they usually get. Sleep disturbance, low mood and constipation often precede the motor symptoms by years, and frequently affect quality of life more than the tremor does.

Resting tremor — shaking of a hand, jaw or leg, most visible when the limb is relaxed
Rigidity — stiffness that makes movement feel resisted
Bradykinesia — slowness, and a gradual shrinking of movement: smaller handwriting, quieter voice, less arm swing
Postural instability — impaired balance and an increasing tendency to fall
Changes in speech and swallowing
Non-motor symptoms — disturbed sleep, loss of smell, constipation, depression and, in later stages, cognitive change

When medication starts to wear off

Levodopa remains the most effective treatment for Parkinson’s and, for the first years, it can work remarkably well. The difficulty comes later. As the disease progresses each dose lasts a shorter time, and the gap before the next one begins to show. Patients start describing their day in terms of “on” periods, when medication is working, and “off” periods, when it is not.

Raising the dose helps the “off” times but often produces dyskinesia — involuntary, flowing movements that appear when levodopa levels peak. The patient is then caught between two unsatisfactory states, and the window in which they feel like themselves narrows.

This pattern — a good response to levodopa that no longer lasts, with dyskinesia at higher doses — is the clearest signal that it is time to discuss surgical options. It is not a sign of having left something too late; it is precisely the stage at which deep brain stimulation was designed to help.

How Parkinson’s is treated

Surgery does not replace medication — it makes medication work better, at lower doses. Equally, no surgical option removes the need for physical therapy. The patients who do best are usually those who treat all of this as one plan rather than a sequence of last resorts.

Approach	What it does	Typically when
Medication management	Levodopa, dopamine agonists, MAO-B inhibitors — replaces or preserves dopamine signalling	First line, at every stage
Deep brain stimulation	Continuous electrical regulation of the affected circuits; extends “on” time, reduces dyskinesia	Motor fluctuations despite optimised medication
MRgFUS	Incisionless lesion for medication-resistant tremor on one side	Tremor-dominant disease; unsuitable for open surgery
Physical therapy	Maintains strength, balance, gait and confidence	From diagnosis onward, continuously
Speech & occupational therapy	Voice projection, swallowing safety, daily-living strategies	As speech or dexterity changes
Psychological support	Addresses depression, anxiety and cognitive change for patient and family	At any stage

Our approach

Assessment starts before you travel. We ask for neurologist reports, recent brain MRIs, a current medication list, and video of the motor symptoms recorded both “on” and “off” medication. From these our neurologists and neurosurgeons form a view on the diagnosis itself, on whether the pattern fits a surgical candidate, and on which target would serve the symptoms that trouble you most.

If the answer is that surgery would not help, we say so. A second opinion that confirms your current treatment is the right one is a useful result, not a wasted consultation.

Treatment options

Deep Brain Stimulation (DBS)

A reversible, adjustable procedure that quiets the abnormal brain signals behind tremor, rigidity and involuntary movement — when medication alone no longer holds the day together.

MR Guided Focused Ultrasound (MRgFUS)

Tremor treated through the intact skull with focused sound waves — no incision, no implanted hardware, and in most cases a result the patient can see on the treatment table.

Medication Management

Before anyone discusses surgery, the medication has to be right. A surprising number of patients arrive with symptoms that are not resistant to treatment — only under-treated.

Physical Therapy & Rehabilitation

The treatment that continues after everyone else has finished. Surgery and medication change what the body can do; rehabilitation decides how much of it you actually get back.

Frequently asked questions

Is Parkinson’s disease hereditary?

Most cases are not directly inherited. A minority are linked to specific genetic variants, and having a close relative with Parkinson’s raises risk modestly — but for the great majority of patients no single cause is identified.

Can Parkinson’s disease be cured?

No treatment currently stops or reverses the underlying loss of dopamine-producing cells. Symptoms, however, can be controlled well and for a long time — and the difference between well-managed and poorly-managed Parkinson’s is measured in years of independence.

Is it too early to consider DBS?

The usual threshold is at least four to five years since diagnosis, with a good levodopa response that has begun to fluctuate. Being assessed does not commit you to surgery, and knowing where you stand is worth having.

My tremor is the main problem. Is that different?

It can be. Tremor-dominant Parkinson’s sometimes responds well to MRgFUS, particularly where one side is far more affected. Where slowness and rigidity are also significant, DBS usually offers more.
