The limitation of treating intrinsic brain pathologies has been circumvented with neurosurgical techniques; however, less invasive approaches may be desirable particularly for widespread or multifocal disease and when long term and repetitive administration is required. This study seeks to investigate the efficacy of focused ultrasound. Patients with either low grade gliomas or neurodegenerative dementias will be evaluated for study candidacy. There are no immediate benefits for patients who choose to participate; however, the information gained from this study will contribute to the research base and help patients in similar situations in the future.
Treatment of intrinsic brain diseases is challenging because brain barrier (BBB) limits the delivery of drugs, particulates and cellular elements such as stem cells to the central nervous system (CNS). This limitation is often circumvented with neurosurgical techniques, however, less invasive approaches may be desirable particularly for widespread or multifocal disease and when long term and repetitive administration is required. The diagnosis for the participants will be either low grade gliomas. A baseline fMRI and follow up routine fMRI's will be taken and evaluated for any changes in perf…
Inclusion Criteria: * Subjects undergoing routine, repetitive MRI scanning for monitoring low grade gliomas * 18 or older Exclusion Criteria: • Cognitive decline with mild cognitive impairment (Clinical Dementia Rating stage 0.5) through moderate dementia CDR stages 1 and 2
With focused ultrasound, there is an expected accentuation of local perfusion and potential temporary opening of the blood brain barrier with the aim is to provide better delivery of therapeutic agents including medication, particulates and cellular elements for treatment of neoplastic, inflammatory and degenerative brain diseases. The present study seeks to investigate differences in perfusion between areas treated and untreated by this modality in order to further explore its use in clinical application for the treatment of brain disease.
