From: Depression in Myotonic Dystrophy type 1: clinical and neuronal correlates

  DM1 (n = 31) Contrast group (n = 47)
Age 41.8 (9.5, 23-58) 43.5 (15.0, 18-64)
Sex 14 M, 17 F 15 M, 32 F
Education (years) 10.9 (2.2, 8-18) 10.4 (1.8, 9-15)
Age at onset 26.2 (8.7, 15-50) 17 (14.5, 0-60)
Disease duration (years) 16.8 (10.7, 3-38) 27 (16, 5-60)
CTG-repeats 578 (401, 100-2000) -
Fatigue* 25 (81%) -
MIRS** 3.6 (0.8, 1-5) -
Grip force (Newton) 104 (48, 20-144) -
Brooke-rating†† 0.5 (1.1) 5.9 (13.9)
  1. * Patients scoring the presence of abnormal fatigue in a self-rating procedure described in Winblad et al, 2005 [9].
  2. ** Muscular Impairment Rating Scale [17]. This score ranges from 1 (no muscular impairment) to 5 (severe proximal weakness).
  3. Scores on a handgrip force measurement using the Grippit instrument. Mean (SD) for healthy controls = 331 (77) Newton [16].
  4. †† Brookes functional test and grading system, zero implies normal function and higher values indicates increasing levels of immobility [18].
  5. Data in Table 1 is presented as mean, standard deviation and range.
