Clinical Trial Description

Parkinson's disease (PD), is one of the commonest neurodegenerative disorders with a severe progressive course and major impact on patients' quality of life. The development of late-onset PD likely results from the interaction of genetic and environmental factors in the context of brain aging. Although several environmental exposures have been implicated, evidence for their causal contributions is limited. PD in Egypt is a rapidly emerging concern as prevalence rose by 40.7% between 1990 and 2016, one of the highest increases in the world. which influences us to dig further in the genetic basis behind the scenes leading to that leap. Cognitive impairment in PD constitutes a major source of disease burden for patients and families, and has a significant negative effect on patients' quality of life. Cognitive impairment without dementia is designated as mild cognitive impairment of PD (PD-MCI), where the activities of daily living are grossly preserved, whereas dementia associated with PD is designated as PD-D. Parkinson's disease dementia is a neurofibrillary tangle degeneration involving the deposition of Alzheimer-type tau, predominantly in the mesial temporal cortex, brainstem, and basal ganglia. The prevalence of Parkinson's Disease Dementia (PD-D) in the general population aged 65 years and over was 0.3 to 0.5%, and 3 to 4% of patients with dementia in the general population were estimated to be due to PD-D. Transcranial magnetic stimulation (TMS) is a noninvasive neurophysiological technique for assessing human motor cortical function. With TMS, the underlying motor cortex is stimulated by an electric current induced by a transient magnetic field, generated in response to the passage of a large current through the stimulating coil located on the patient's scalp. ;
