Parkinson’s Disease is an age-related chronic, progressive neurodegenerative disorder that primarily affects movement is the progressive loss of dopaminergic neurons in the substantia nigra pars compacta (midbrain). which is responsible for controlling movement and coordination. This condition is best known for how it affects muscle control, balance and movement, it can also cause a wide range of other effects on your senses, thinking ability, mental health and more..This leads to:
Formation of Lewy bodies, abnormal intracellular aggregates made of the protein alpha-synuclein, which are toxic to neurons.
Dopamine depletion in the striatum, a key component of the basal ganglia, which regulates voluntary motor control.
Parkinson’s disease
Major Pathological Processes:
Pathology
Mitochondrial dysfunction – Impaired complex I of ETC.
Protein aggregation – Due to dysfunctional autophagy and lysosomal path
What is the difference between Parkinson’s disease vs. parkinsonism?
“Parkinsonism” is an umbrella term that describes Parkinson’s disease and conditions with similar symptoms. It can refer not only to Parkinson’s disease but also to other conditions like multiple system atrophy or corticobasal degeneration.

Parkinson’s disease
Definition
A specific neurodegenerative disease caused primarily by dopamine deficiency in the substantia nigra.
Cause
Idiopathic (unknown exact cause), often linked to loss of dopaminergic neurons and Lewy body formation.
Underlying Pathology
Alpha-synuclein aggregation (Lewy bodies), dopamine neuron loss in substantia nigra.
Typically shows good improvement, especially early in disease.
Disease Progression
Slowly progressive, over many years.
Non-Motor Symptoms
Present (e.g., loss of smell, depression, REM sleep behavior disorder).
Examples
Idiopathic Parkinson’s Disease (only one type).
Neuroimaging
DaTscan: Decreased dopamine transporter uptake.
Treatment
Levodopa, dopamine agonists, MAO-B inhibitors, DBS in later stages.
Prognosis
Generally better, long-term management possible.
Parkinsonism (Parkinsonian Syndromes)
Definition
A broad clinical syndrome with signs similar to PD (e.g., tremor, rigidity), but can have many different causes.
Cause
Can be due to: <ul><li>Other neurodegenerative diseases (atypical Parkinsonism)</li><li>Medications (drug-induced)</li><li>Stroke, trauma, toxins</li></ul>
Underlying Pathology
Depends on cause: <ul><li>No Lewy bodies in drug-induced forms</li><li>Different proteinopathies in atypical types (e.g., tau in PSP)</li></ul>
Motor Symptoms
Similar motor signs, but often: <ul><li>More symmetric</li><li>More rapid progression</li><li>Less tremor</li></ul>
Response to Levodopa
Poor or minimal response in most forms of secondary or atypical Parkinsonism.
Disease Progression
Often faster progression (especially atypical forms like PSP or MSA).
Non-Motor Symptoms
May be less common or more rapidly developing cognitive/neurological issues.
“Fitness” is a broad term that means something different for each and every individual, but it refers to your own optimal health and overall well being. Being fit not only means physical health, but emotional and mental health too. Fitness is vital for overall health boosting physical and mental well being reducing the risk of … Read more
Spine mobility refers to the ability of the vertebral column (the spine) to move freely through its natural ranges of motion: Flexion (bending forward), Extension (bending backward), Lateral flexion (side bending), Rotation (twisting) Good mobility ensures efficient movement, distributes mechanical loads evenly, and reduces injury risk. Lets look at the anatomy of spine Anatomy of … Read more
The physical therapy component of the interdisciplinary treatment approach focuses on general reconditioning with graded exposure to activity, gradual reduction of fear-avoidance behaviors, and incremental elimination of other pain behaviors These involve collaboration among professionals from various fields—medicine, nursing, occupational therapy, speech-language pathology, psychology, social work, nutrition, and others—to address the full scope of a … Read more
Objective Structured Clinical Examination (OSCE) is a widely used method for assessing clinical competence in healthcare education, including physiotherapy. It is a practical exam used in physiotherapy education to test clinical and professional skills in a very organized way. A performance-based assessment in which physiotherapy students rotate through a series of stations, where they are … Read more
Strength Training (Resistance Training): A form of physical activity designed to improve muscular strength and endurance by exercising a muscle or a muscle group against external resistance. A systematic approach to physical conditioning that uses resistance to induce muscular contractions. The goal is to develop muscular strength, hypertrophy (growth), endurance, and power. Common Resistance Forms: Principles of Strength Training Principle Description Progressive … Read more
International day of yoga (IDY), Observed annually on June 21, chosen as it’s the summer solstice—the longest day in the Northern Hemisphere—symbolizing harmony between humanity and nature. Yoga is an ancient practice that originated in India over 5,000 years ago, designed to bring harmony between body, mind, and spirit. The word “yoga” is derived from the … Read more
My husband was diagnosed of Parkinsons disease 2 years ago, when he was 49. He had a stooped posture, tremors, right arm does not move and also a pulsating feeling in his body. He was placed on Senemet for 8 months and then Sifrol was introduced and replaced the Senemet, during this time span he was also diagnosed with dementia. He started having hallucinations, lost touch with reality. Suspecting it was the medication I took him off the Siferol (with the doctor’s knowledge) and started him on PD-5 natural herbal formula we ordered from AKNNI HERBAL CENTRE, his symptoms totally declined over a 3 weeks use of the AKANNI HERBAL Parkinson’s disease natural herbal formula. He is now almost 51 and doing very well, the disease is totally reversed! (Visit w w w.aknniherbscentre .com)
