Exploring the Complexities of Parkinson’s Disease
Abstract: Parkinson’s disease (PD) is a neurological disorder, primarily affecting older adults, marked by both motor and non-motor symptoms. This review explores PD as a multisystem disorder that influences the central, enteric, and autonomic nervous systems, along with the immune system and gastrointestinal tract. Key pathogenic features include the degeneration of dopamine-producing neurons in the substantia nigra and the formation of Lewy bodies containing misfolded α-synuclein proteins. The bradykinesia, tremors, stiffness, …

A Review on Applications of Artificial Intelligence (AI) in Parkinsons’s Disease Diagnosis and Treatment and Its Future Challenges
Abstract: Parkinson’s disease (PD) is a long-term, progressive neurodegenerative disorder that mainly occurs in people older than 60 years, affecting nearly 1% of this population. It is chiefly marked by the loss of dopaminergic neurons in the substantia nigra, a crucial brain region responsible for controlling motor functions. The resultant dopamine deficiency significantly disrupts motor control, manifesting in clinical symptoms such as tremors, bradykinesia, muscle rigidity, and postural instability. While PD …

Unraveling the Nexus: Parkinson's Disease, Alpha-synuclein, Desulfovibrio, and the Gut Microbiome
Abstract: Parkinson's disease (PD) is now recognized as a chronic condition which is once considered a highly intricate disorder involving the central, autonomic, and enteric nervous systems. The prevailing perspective attributes the disease by the formation of Lewy bodies, primarily triggered by the misfolding of α-Synuclein, leading to the demise of dopaminergic neurons in the substantia nigra. Constipation, one of the most common non-motor symptoms in PD patients, is believed to …

Rotenone effects on the human body with reference to neurological disorder
Abstract: It has been claimed that the well–known neurotoxic pesticide rotenone, which is known to block the mitochondrial complex I, is strongly linked to the pathophysiology and etiology of Parkinson's disease (PD) in humans. There have been numerous analyses in the past and are still being conducted to establish a relationship between the two in order to completely comprehend the level of harm brought on by rotenone. Numerous laboratory studies shown …

Neurodegeneration and Cognitive Decline: Causes, Consequences, and Treatment Approaches
Abstract: Neurodegenerative diseases gradually destroy nerve cells, often leading to fatal outcomes. The phrase includes a wide range of clinical problems, such as a variety of Neurological conditions include movement disorders, like Parkinson’s disease (PD) and progressive cognitive impairments, with Alzheimer’s disease (AD) being the most common among them. A loss of neurones and synaptic connections, typically in later life, is a prevalent feature of Usually, the onset and development of …
