MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
(1) In-vivo quantification of nicotinic acetylcholine receptor availability in neurodegenerative diseases (2) To find diagnostic patterns of altered in-vivo nicotinic acetylcholine receptor binding in neurodegenerative disease |

E.2.2 | Secondary objectives of the trial |
To assess whether these patterns of altered nicotinic acetylcholine receptor binding in neurodegenerative diseases: (1) correlate with clinical parameters, (2) are useful for early diagnosis of neurodegenerative diseases and prediction of clinical outcome (3) can improve our understanding of individual drug therapy (4) are associated with environmental parameters (e.g. tobacco smoking, caffeine intake, metabolic disease) and genetic variables
