Introduction  

As a General Practitioner (GP), I encounter various medical conditions daily, each with its unique challenges and implications. One condition that merits special attention is Parkinson’s disease. A progressive neurological disorder, Parkinson’s affects millions worldwide, and the number of cases in the UK is no exception. In this blog, we will explore the essential aspects of Parkinson’s disease, its symptoms, diagnosis, and available treatment options.  

Understanding Parkinson’s Disease  

Parkinson’s disease is a chronic progressive disorder that primarily affects the brain’s movement control centre. It occurs when certain nerve cells in the brain, specifically the substantia nigra, begin to malfunction and degenerate. These nerve cells produce dopamine, a neurotransmitter crucial for smooth and coordinated movement.  

Symptoms  

The hallmark symptoms of Parkinson’s disease result from the gradual decline in dopamine levels, leading to motor and non-motor symptoms. Some of the common motor symptoms include:  

  • Tremors: Involuntary shaking, often starting in the hands, fingers, or arms while at rest;
  • Bradykinesia: Slowness of movement, making everyday tasks more challenging and time-consuming; 
  • Muscle Rigidity: Stiffness and tension in muscles, causing discomfort and difficulty with mobility;
  • Postural Instability: Unsteadiness and balance issues, increasing the risk of falls;
  • Non-motor symptoms: These can be easily overlooked but must not be underestimate. These include depression, anxiety, sleep disturbances, constipation, and cognitive changes.

The impact of these symptoms can affect so many simple actions that we otherwise take for granted; writing, eating, swallowing, speech, walking , sleeping, toileting to name but a few.  

Diagnosis  

Diagnosing Parkinson’s disease is complex and requires expertise, such as a neurologist. As a GP, my role involves identifying the initial symptoms and referring those patients for further evaluation. Infact usually as a GP I don’t initiate any medication until that specialist diagnostic evaluation has taken place, so that the neurologist can make his or her own judgement without interference of medicines. The diagnosis is made based on the patients story, a thorough neurological examination, and the exclusion of other similar conditions. Observations of friends & family can be very useful.   

Treatment  

Although there is no cure for Parkinson’s disease, various treatment options are available to manage its symptoms and enhance the patient’s quality of life. Treatment plans are tailored to each individual and may include:  

Medications: Dopamine replacement therapies, such as levodopa, help alleviate motor symptoms and improve movement control. Medicines for improving mood, dizziness, constipation or urinary issues are sometimes needed too. It is very much a tailored approach, that changes over time as the condition evolves in that individual.   

Physical Therapy: Physical exercises and occupational therapy can enhance mobility, balance, and daily functioning.  

Lifestyle Modifications: Regular exercise, a balanced diet, and stress management techniques can complement medical treatment.  

Deep Brain Stimulation (DBS): For some advanced cases, DBS surgery may be considered to control specific symptoms.  

Support for Patients and Families  

As a GP, I understand that having Parkinson’s disease can be overwhelming for both patients and their families. Providing emotional support, empathy, and information about available resources is crucial in helping them navigate this journey. Patients can benefit from joining local & national support groups and connecting with others who share similar experiences. Here in Waltham Forest we are lucky to have the input of a specialist Parkinson’s community nurse.   

Summary  

Parkinson’s disease presents unique challenges, but with early detection and appropriate management, patients can maintain a fulfilling life. As a UK GP, I encourage everyone to recognize potential symptoms, and seek medical advice if its suspected. Patients and their carer’s, together with support from healthcare professionals,  we can better manage Parkinson’s and improve the overall well-being of those affected by this condition as well as their care givers.
