Trial Outcomes & Findings for Effect of Repetitive Transcranial Magnetic Stimulation on Language in Alzheimer's Disease (NCT NCT00814697)

NCT ID: NCT00814697

Last Updated: 2014-01-28

Results Overview

Cognitive assessment tasks - Boston Diagnostic Aphasia Examination (BDAE), CFL Category naming (CFL), Mini-Mental State Examination (MMSE) - were administered and scored according to standard procedures before, during and 4 weeks after rTMS. Higher scores are associated with better cognition; No absolute cut-offs were used here as the outcomes were not categorically assessed. Total possible score ranges by test, lowest to highest: BDAE - 0 to 15 CFL - 0 to 62 MMSE - 0 to 30 Full range data and means presented below represents range of scores at 4-weeks post-rTMS treatments.

Participant Flow

All patients were recruited from a tertiary memory disorders practice. Patients were diagnosed as having probable or possible Alzheimer's Disease (AD), using the National Institute of Neurological and Communicative Disorders and Stroke and Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria.

Exclusion criteria included newly diagnosed AD, pacemaker placement, a history of implanted metal object, seizures or epilepsy, a recent history of migraines, uncontrolled depression and those on medications lowering the seizure threshold.
