Demographic and clinical baseline characteristics according to baseline MR subtypes (non-AD or AD type, responding or not to MR criteria of conversion)
| Baseline clinical variables | Baseline MR profiles* |
|||
|---|---|---|---|---|
| Possible AD (non-converters) | AD predementia (converters) | Possible cerebrovascular dysfunction (non-converters) | Non-AD predementia (converters) | |
| Age | 73 ± 7 | 78 ± 2 | 68 ± 5 | 75 ± 5 |
| Females/males | 2/2 | 0/3 | 11/3 | 3/3 |
| Years of schooling | 16 ± 3 | 10 ± 6 | 13 ± 4 | 13 ± 5 |
| Cardiovascular risk score | 1 ± 1 | 2 ± 1 | 1 ± 1 | 1 ± 1 |
| MMSE total score | 27 ± 1 | 27 ± 1 | 28 ± 1 | 28 ± 1 |
| Grober-Buschke test, DTR score | 14 ± 1 | 12 ± 5 | 16 ± 1 | 14 ± 3 |
| Trail Making Test, substraction score | 97 ± 45 | 36 ± 6 | 64 ± 35 | 130 ± 92 |
| Mobility scores** | 0 ± 1 | 1 ± 0 | 2 ± 2 | 4 ± 2 |
*
Notes: Patients with “mixed” MR presentations characterized by coexistence of MR profiles of at least possible AD and possible cerebrovascular are not included in these subgroups;
**
mobility scores are presented only in patients with no known cause of mobility (2 of the 4 patients with pure possible AD MR profile, all the 3 patients with pure AD predementia MR profiles, all the 14 patients with MR profile of possible pure cerebrovascular dysfunction, and all the 6 patients with pure predementia non-AD profiles).
