Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to assess the therapeutic role of rTMS on parkinson's patients with cognitive impairment. Patients diagnosed with Parkinson's Disease and cognitive impairment will be recruited. All patients will be admitted and will be allocated randomly into two groups one of which will receive real sessions of high frequency rTMS for each hemisphere for 10 consecutive sessions totally over period of 10 days with repeated booster sessions every month during the period of follow up. The other will receive sham sessions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to assess the therapeutic role of rTMS on parkinson's patients with cognitive impairment. Thirty PD patients with cognitive impairment using United Kingdom (UK ) bank criteria for PD will be recruited from outpatient clinic in Assiut University. All patients will be admitted at Neuropsychiatric Department, Assiut University Hospital/ Assiut, Egypt.Each patient fulfilled the inclusion criteria as having score less than 24 on Mini-Mental Status Examination will be recruited. The patients will be allocated randomly into two groups one of which will receive real sessions of high frequency rTMS (25 HZ), with intensity of 80% of resting motor threshold detected from the hand motor area, with total 2000 pulses for each hemisphere for 10 consecutive sessions totally over period of 10 days with repeated booster session every month during the period of follow up among three months. The other will receive sham sessions. All subjects will be followed up by selected clinical rating scales at different intervals pre session, post 10 sessions, and after one, two and three months.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Real rTMS

Real rTMS high frequency stimulation (25 HZ), with intensity of 80% of resting motor threshold detected from the hand motor area, with total 2000 pulses for each hemisphere on the hand motor area for 10 consecutive sessions totally over period of 10 days.

Group Type ACTIVE_COMPARATOR

repetitive Transcranial Magnetic Stimulation

Intervention Type DEVICE

By defining intensity of 80% of the resting Motor Threshold detected from motor area for Rt Abductor digiti minimi (ADM), we will apply repetitive Transcranial Magnetic Stimulation (rTMS) using 70-mm diameter air-cooled figure-of-8 coil and SuperRapid2 Magnetic Stimulator with high frequency (25Hz), Stimuli will be delivered for total 2000 pulse (divided on 50 trains with 40 pulses per train with inter-train interval 30 seconds) for each hemisphere (coil placed tangential over the optimal position of hand motor area detected for Real group and the same coil placed perpendicular with hand of coil pointing upward over occipital cortex for Sham group). Sessions will be consecutive for ten days period with repetition of consecutive 5 sessions as boosting doses on 5 days period over the follow up visits every month for the next 3 months.

Sham rTMS

Sham rTMS high frequency stimulation (25 HZ), with intensity of 80% of resting motor threshold detected from the hand motor area, with total 2000 pulses for each hemisphere with coil perpendicular on scalp for 10 consecutive sessions totally over period of 10 days.

Group Type SHAM_COMPARATOR

repetitive Transcranial Magnetic Stimulation

Intervention Type DEVICE

By defining intensity of 80% of the resting Motor Threshold detected from motor area for Rt Abductor digiti minimi (ADM), we will apply repetitive Transcranial Magnetic Stimulation (rTMS) using 70-mm diameter air-cooled figure-of-8 coil and SuperRapid2 Magnetic Stimulator with high frequency (25Hz), Stimuli will be delivered for total 2000 pulse (divided on 50 trains with 40 pulses per train with inter-train interval 30 seconds) for each hemisphere (coil placed tangential over the optimal position of hand motor area detected for Real group and the same coil placed perpendicular with hand of coil pointing upward over occipital cortex for Sham group). Sessions will be consecutive for ten days period with repetition of consecutive 5 sessions as boosting doses on 5 days period over the follow up visits every month for the next 3 months.
