Background And Purpose:
Non-motor manifestations are frequently overlooked in degenerative disorders and little is known about their frequency and clinical relevance in SPG4 hereditary spastic paraplegia (SPG4-HSP).
Methods:
Thirty patients with SPG4-HSP and 30 healthy controls answered the Modified Fatigue Impact Scale, Epworth Sleepiness Scale, Brief Pain Inventory and Beck Depression Inventory. Student's t test was used to compare groups and linear regression was used to assess correlations.
Results:
Patients had higher fatigue scores than controls (31.0 ± 16.5 vs. 14.5 ± 16.0, P = 0.002) as well as pain (3.4 ± 2.7 vs. 1.0 ± 1.6, P = 0.001) and depression (12.7 ± 8.9 vs. 4.4 ± 3.8, P < 0.001, respectively). Fatigue was associated with depression and possibly with disease severity (P = 0.008 and 0.07, respectively).
Conclusions:
Fatigue, pain and depression are frequent and often severe manifestations in patients with SPG4-HSP.
