Research study establishes the link
It will come as no surprise to many with HSP, their families, loved ones and others who care for them that fatigue, pain and depression occur frequently and often severely in HSPers compared with healthy, non-HSP-affected people.
The statistical difference between the 2 populations is at a ‘highly significant’ level.
This supports the findings of an earlier study from 2009 where it was found that over half the population of HSPers in the study were depressed. That study also linked severity of depression with loss of mobility.
Even though these results seem self-evident, don’t underestimate the importance of this research as it establishes an evidence base for these outcomes associated with having HSP. Your doctors as well as allied health professionals such as your physio now have a good clinical reason to treat, or refer for treatment of, these outcomes of fatigue, pain and depression.
These results also change the nature of any request you might make of your doctor or allied health professional to investigate these issues when you report them, now that they are medically established by this research as different from non-HSPers reporting fatigue, pain or depression.
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).
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.
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).
Fatigue, pain and depression are frequent and often severe manifestations in patients with SPG4-HSP.
