Results of the first study to evaluate the relationship between childhood trauma and PD investigators found that the relationship appears to be dose dependent. Patients with PD who reported more than one ACE all experienced a statistically significant decrease in QOL, and for each additional ACE, there was significant worsening of motor symptoms.
This study supports a recent-call to-action paper in JAMA Neurology encouraging adoption of “trauma-informed neurology,” study investigator Indu Subramanian, MD, clinical professor, department of neurology, University of California, Los Angeles, said in an interview.
“We need to start asking about ACEs in everyone. It should be part of our medical intake,” said Dr. Subramanian, who is also the director of the Southwest Parkinson’s Disease Research, Education, and Clinical Center, West Los Angeles Veterans Affairs Medical Center.
The study was published online in Neurology: Clinical Practice.
Hard on the mind and body
A robust body of literature has clearly established a connection between ACEs, which include physical and emotional abuse, neglect, and household dysfunction, and negative physical health outcomes across the lifespan. These include stroke, dementia, diabetes, cancer, cardiovascular disease, autoimmune disorders, hypertension, and premature death as well as psychosocial health outcomes such as anxiety, depression, substance use, and suicide.
However, until now, the effects of childhood trauma have not been evaluated in a PD population.
As part of the MVP study, 712 adults with PD responded to an online survey asking about childhood trauma.
As anticipated, patients with the least reported childhood trauma reported the highest current QOL and lowest patient-reported motor and nonmotor symptom burden compared with peers with higher reported childhood trauma, the researchers reported.
PD symptom burden increased and QOL decreased as the number of ACEs increased.
Patients with ACE scores of 4 or higher reported greater PD symptom severity for 45% of the variables assessed, including apathy, muscle pain, daytime sleepiness, restless leg syndrome, depression, fatigue, comprehension, and anxiety (P < .05), compared with peers with trauma scores of 0.
Limitations of the study included the cross-sectional nature, which prevents making any causal determinations. Also, the ACE questionnaire, because it is self-reported and a retrospective collection of data, introduces the risk for recall bias. In addition, 65% of respondents were women, and racial and ethnic minority groups were not well represented.
Looking ahead, Dr. Subramanian and coauthors believe future research should “attempt to include more diverse populations, attempt improve the response rate of these sensitive questions and, most importantly, determine whether the adverse outcomes associated with childhood trauma can be mitigated with lifestyle modification, psychosocial support, and intervention in adulthood.”
“As a trauma-informed approach, something sorely lacking yet needed in the field of movement disorders, clinicians can proactively screen for ACEs while being mindful to avoid retraumatization,” they suggested. “They can begin to identify how ACEs may physiologically contribute to PD symptom and focus on targeting appropriate interventions that may improve outcomes.”
