The Effect of Different Types of Focus Instructions in Parkinson's Rehabilitation

Parkinson's disease is the most common progressive neurodegenerative movement disorder. Common movement impairments in Parkinson's include balance and walking difficulties. These impairments lead to falls, increased levels of functional dependency, and a decrease in quality of life. Exercise in Parkinson's patients improves their functional symptoms in daily life, enhancing both motor and non-motor skills, and consequently increases their quality of life. Recently, various additional methods have been developed to increase the effectiveness of exercise in Parkinson's rehabilitation and to contribute to motor skills. Focus of attention instructions are fundamental concepts in motor function learning. External focus of attention has been shown to facilitate motor function development, reduce postural instability, and improve dual-task walking by being easier to remember. In Parkinson's patients who experience freezing phenomena, internal focus of attention instructions enhance walking stability and movement control, thereby reducing the risk of falls. However, there are no studies on the combined focus of attention instructions in Parkinson's patients. This study is designed as a randomized controlled, single-blind, prospective trial to examine the effects of a combination of internal and external focus of attention instructions on walking, balance parameters, quality of life, and patient satisfaction levels, taking into account the presence of freezing phenomena in Parkinson's patients.

Feasibility and Efficacy of Attentional-Control Training in Sickle Cell Disease

Children with sickle cell disease (SCD) exhibit significantly reduced cognitive functioning (often difficulties with attention) compared to peers and siblings without SCD. EndeavorRx (Akili Interactive Labs: Boston, MA) is an FDA-approved home-based, electronic attentional-control training program designed to treat attention problems in youth. Users access EndeavorRx on a tablet device for 25-30 minutes each day, 5 days per week, for 4 weeks. The program involves training in a game-like environment that repeatedly challenges attentional-control abilities and adapts to user performance, becoming more difficult over time as performance improves. This pilot study is examining the feasibility, acceptability, and preliminary efficacy of EndeavorRx in a sample of 20 children with SCD ages 8-16 who are being treated with chronic blood transfusion therapy.

Feasibility/Acceptability of Attentional-Control Training in Survivors

This is a multicenter pilot randomized controlled trial, with an active control condition, of the feasibility, acceptability, and preliminary efficacy of EndeavorRx in a cohort of survivors of acute lymphoblastic leukemia or brain tumor ages 8-16 who are \> 1 year from the end of therapy.

Maternal Choline Supplementation and Offspring Cognition in Adolescence

The goal of this 13-year follow up of a randomized control trial is to study the effect of maternal choline supplementation on offspring cognition in adolescence. The main question\[s\] it aims to answer are: Does a higher dose of maternal choline choline (930 mg/d day supplementation) lead to improved cognition in adolescence including hippocampal-dependent episodic memory and executive functioning when compared to lower dose supplementation (480 mg/d). In this follow-up of a clinical trial participants will complete online cognition testing and emotion testing.
