Brief Summary:
The long-term goal of this project is to examine the effects of cystic fibrosis (CF) and cystic fibrosis related diabetes (CFRD) on brain structure and function

Condition or disease
Cystic Fibrosis

Detailed Description:

A growing body of evidence suggests that hyperglycemia in type 1 and type 2 diabetes is associated with alterations in brain structure and cognitive impairment. People with cystic fibrosis related diabetes (CRFD) are exposed to hyperglycemia as seen in other forms of diabetes, and cystic fibrosis is also associated with chronic systemic inflammation. Both hyperglycemia and chronic inflammation have been postulated to affect brain structure and function. Cystic fibrosis trans-membrane conductance regulator (CFTR). protein is widely expressed in the neurons of the brain including in the hippocampus The hippocampus plays an essential role in learning and memory processing and is thought to be particularly vulnerable to effects of metabolic stressors. The expression of CFTR in neurons has several potential implications for central nervous system function, including cognition.

The long-term goal of this project is to examine the effects of cystic fibrosis (CF) and cystic fibrosis related diabetes (CFRD) on brain structure and function.

Cystic Fibrosis
Subjects with cystic fibrosis
matched healthy controls

Primary Outcome Measures :
  1. MRI outcome [ Time Frame: baseline ]
    Measure the differences in the microstructure (fractional anisotropy) of hippocampus, comparing subjects with cystic fibrosis and healthy controls

Secondary Outcome Measures :
  1. Cognitive function [ Time Frame: baseline ]
    Compare performance on neurocognitive function testing in subjects with cystic fibrosis and healthy controls. Multiple cognitive domains will be examined including intellectual function, processing speed. attention and memory.
