NCT00714636
The purpose of a CSF repository is to collect samples of spinal fluid from controls and patients with neurologic disorders including but not exclusively ALS, Dementia, CRPS, neuropathies, and other neuromuscular diseases. This CSF repository will allow the use of CSF in biochemical studies of various neurologic diseases. It would also provide a supply of the necessary normal and disease control patients. CSF would be obtained from patients who are undergoing spinal taps for other reasons including diagnosis, treatment, or participation in clinical trials. We are proposing to collect an additional \< 3 ml of CSF from a lumbar puncture that is already being performed for diagnostic or therapeutic reasons, in order to store it in our laboratory for use in future research studies. No lumbar punctures will be initiated specifically for this protocol.
NCT02449629
This study uses a transformative multiphasic mixed-methods research design that incorporates elements of the following designs: * Sequential: a secondary data analysis was conducted, using data from ATN 039, ATN 086, and ATN 106, to influence the development of the qualitative interview and quantitative survey instruments for primary data collection. * Convergent parallel: concurrent collection and analysis of both qualitative and quantitative primary data that will be combined to address the study objectives.
