Parkinson's Disease: Physiology, Cause, Management and Treatment

Image
Parkinson’s Disease Definition Parkinson’s disease (PD) is a chronic, progressive neurodegenerative disorder of the central nervous system characterized mainly by resting tremor, rigidity,  slowness of movement , and postural instability, due to degeneration of dopaminergic neurons in the brain. Physiology (Pathophysiology) Parkinson’s disease primarily affects the basal ganglia, especially the substantia nigra pars compacta. There is progressive loss of dopamine-producing neurons. Dopamine deficiency leads to imbalance between dopamine and acetylcholine in the striatum. This imbalance results in impaired motor control. Resulting motor effects: ↓ Dopamine → ↓ stimulation of motor cortex → impaired voluntary movement Causes (Etiology) Primary (Idiopathic) •Most cases are idiopathic (unknown cause) •Age-related neuronal degeneration Secondary Causes •Genetic mutations (e.g., SNCA, LRRK2, PARK genes) •Environmental toxins (pesticides, MPTP) •Head injury •Drugs (antipsychot...

What are different Types Of Symbiotic Relationships ?

Image
Symbiotic relationships are close relationship or interactions between different species, primarily categorized as Mutualism (both benefit), Commensalism (one benefits, other unaffected), and Parasitism (one benefits, other harmed). Other forms include Amensalism (one harmed, other unaffected) and Competition (neither benefits), with some interactions being necessary or optional. Major Types of Symbiosis 1.Mutualism (++): Both species gain advantages from the interaction. Example: Clownfish get protection from predators, while the anemone gets food scraps and cleaned. 2.Commensalism (+0):  One organism benefits, while the other experiences no significant effect. Example: Cattle egrets eat insects stirred up by cattle, benefiting from the meal without affecting the cattle. 3.Parasitism (+-):  One organism (parasite) benefits by living on or in another (host), harming the host. Example: Fleas or ticks feeding on a dog's blood. Other Important ...

What is Butterfly Effect ?

Image
The Butterfly Effect  refers to a concept in chaos theory, suggesting that small changes in a system can lead to significant and unpredictable consequences over time. The term was popularized by meteorologist Edward Lorenz in the 1960s.  He used the metaphor of a butterfly flapping its wings in Brazil, potentially setting off a chain of events that could lead to a tornado in Texas.  The core idea is that even a tiny alteration in initial conditions can result in vastly different outcomes, making long-term prediction of complex systems (like weather or ecosystems) very difficult.  This concept highlights the sensitivity of systems to initial conditions, emphasizing the unpredictability inherent in chaotic systems.
