Brown J, Pengas G, Dawson K, Brown LA, Clatworthy P.. BMJ (Clinical research ed.), 2009-06-09
Topic: Amyloid, tau and blood-test diagnosis
Objective To evaluate a cognitive test, the TYM ("test your memory"), in the detection of Alzheimer's disease. Setting Outpatient departments in three hospitals, including a memory clinic. Participants 540 control participants aged 18-95 and 139 patients attending a memory clinic with dementia/amnestic mild cognitive impairment.

Key findings
- Setting Outpatient departments in three hospitals, including a memory clinic.
- Participants 540 control participants aged 18-95 and 139 patients attending a memory clinic with dementia/amnestic mild cognitive impairment.
- Intervention Cognitive test designed to use minimal operator time and to be suitable for non-specialist use.
- Main outcome measures Performance of normal controls on the TYM.
Why it matters
This study evaluated a self-administered cognitive test called the TYM for detecting Alzheimer's disease. It is about a screening tool, not about treating, curing or preventing the disease.
