Parkinson’s patients sometimes experience dizziness when standing primarily because of a condition called **orthostatic hypotension**. This means their blood pressure drops suddenly upon standing up, leading to reduced blood flow to the brain and causing lightheadedness or dizziness. In Parkinson’s…
Parkinson’s disease can indeed cause problems with vision, including double vision and blurry sight, although these symptoms are not the most common or primary features of the disease. Parkinson’s is primarily known as a movement disorder caused by the loss…
Parkinson’s disease affects eating and nutrition in multiple complex ways, primarily due to its impact on both motor and non-motor functions that are essential for the process of eating, swallowing, digestion, and nutrient absorption. These effects can lead to challenges…
Parkinson’s patients often feel socially isolated due to a complex interplay of physical, emotional, cognitive, and societal factors that affect their ability to connect with others. The disease itself causes motor symptoms like tremors, stiffness, slowed movements, and difficulty with…
Parkinson’s disease can indeed cause hallucinations during sleep, and this phenomenon is linked to the complex ways the disease affects the brain and sleep patterns. People with Parkinson’s often experience various sleep disturbances, including vivid dreams, nightmares, and hallucinations that…
Parkinson’s disease (PD) profoundly affects long-term brain function by causing progressive changes in both motor and non-motor areas of the brain, leading to a complex decline in cognitive abilities, sensory processing, and overall brain health. While it is primarily known…
Parkinson’s patients sometimes struggle with multitasking because the disease affects specific brain areas responsible for executive functions, which include planning, organizing, and managing multiple tasks at once. Parkinson’s primarily damages the basal ganglia and frontal lobes—regions crucial for coordinating thought…
Parkinson’s disease can indeed cause **confusion in the evening hours**, a phenomenon often referred to as “sundowning.” This is a state where symptoms such as confusion, agitation, hallucinations, or increased cognitive difficulties become more pronounced during late afternoon or evening.…
Parkinson’s disease profoundly affects handwriting and daily tasks primarily through its impact on motor control. One of the hallmark signs related to handwriting is called **micrographia**, which means abnormally small, cramped, and often progressively shrinking handwriting. This happens because Parkinson’s…
Parkinson’s patients often have reduced arm swing when walking because of the core motor symptoms caused by the disease, primarily rigidity, bradykinesia (slowness of movement), and impaired motor control. These symptoms affect the muscles and nervous system pathways that normally…
