Transcranial Direct Current Stimulation of the Temporal Cortex in Survivors of Childhood Acute Lymphoblastic Leukemia (ALL)

2019-10-02 07:21:47 | BioPortfolio

Summary

Brief Overview: Children and adolescents diagnosed with cancer will experience problems with learning, memory and attention during and after completing their cancer therapy. There are many factors that contribute to this problem, but investigators have recently identified that chemotherapy agents used in treating Acute Lymphoblastic Leukemia (ALL) may disrupt normal brain development.

A novel device has been developed that may help correct this disruption. Direct Current Stimulation (DCS) uses a very low level of constant electrical current to stimulate specific parts of the brain. It has been used in patients with stroke to great benefit. Our study at St. Jude Children's Research Hospital is designed to see if this technique will benefit survivors of childhood cancer. Specifically, investigators wish to see if stimulating one part of the brain gives a greater benefit than stimulating another part of the brain.

Primary Objective

Evaluate the feasibility of conducting repeated on-site Transcranial Direct Current Stimulation (tDCS) in children who are long-term survivors of

Secondary Objectives

- To estimate the potential efficacy for powering a future larger study using tDCS to improve cognitive performance in children by suppressing over connected neural hubs in long-term survivors of childhood ALL.

- To compare the performance of anodal stimulation of the frontal lobe to cathodal suppression of the superior temporal lobe on cognitive performance.

Description

Participants will be randomly assigned to one of three intervention arms. Two brief stimulation periods will be conducted on day one. One brief stimulation will be scheduled in the morning and a second brief stimulation will be scheduled in the afternoon. A final stimulation will be conducted on day two. Direct Current Stimulation will be applied for 20 minutes for each stimulation period. Brief neurocognitive testing will be conducted during each stimulation session.

Medical and Biotech [MESH] Definitions

Procedures, surgery, or other treatment without consent of person or persons receiving treatment.

Withholding or withdrawal of a particular treatment or treatments, often (but not necessarily) life-prolonging treatment, from a patient or from a research subject as part of a research protocol. The concept is differentiated from REFUSAL TO TREAT, where the emphasis is on the health professional's or health facility's refusal to treat a patient or group of patients when the patient or the patient's representative requests treatment. Withholding of life-prolonging treatment is usually indexed only with EUTHANASIA, PASSIVE, unless the distinction between withholding and withdrawing treatment, or the issue of withholding palliative rather than curative treatment, is discussed.

A vasodilator that also has bronchodilatory action. It has been employed in the treatment of angina pectoris, in the treatment of asthma, and in conjunction with ultraviolet light A, has been tried in the treatment of vitiligo. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1024)

A treatment method in which patients are under direct observation when they take their medication or receive their treatment. This method is designed to reduce the risk of treatment interruption and to ensure patient compliance.

An internationally recognized set of published rules used for evaluation of cancer treatment that define when tumors found in cancer patients improve, worsen, or remain stable during treatment. These criteria are based specifically on the response of the tumor(s) to treatment, and not on the overall health status of the patient resulting from treatment.
