There is a significant association between primary hyperhidrosis and the prevalence of depression, anxiety, and attention deficit disorder (ADD), regardless of a patient’s gender or age, according to research presented at the 2019 American Academy of Dermatology Annual Meeting, held March 1-5 in Washington, DC.

Primary hyperhidrosis is a disorder with a significant impact on patient quality of life. The current study was designed to illuminate the correlation between anxiety, depression, and ADD with primary hyperhidrosis location and severity. Patients (N=500) diagnosed with primary hyperhidrosis at a single site between 2011 and 2018 were included in the study, and their age at the time of initial evaluation, age at onset, gender, Hyperhidrosis Disease Severity Scale (HDSS), and primary hyperhidrosis location were recorded.Patients were identified as having depression, anxiety, or ADD if they reported their diagnosis when filling out their intake forms, if they had a clinical note documenting the diagnosis, if they had an ICD9 code, or if they were taking ADD-specific medication.

Of the total cohort, 13.8% of patients were identified as having anxiety, 12.4% as having depression, and 6.4% as having ADD, which reflects a significantly higher prevalence than found in the general population. Although no association was found between overall HDSS severity or hyperhidrosis location and the prevalence of psychiatric conditions, there were positive correlations found between the number of anatomical sites involved in hyperhidrosis and the prevalence of psychiatric conditions.

Study investigators concluded that, “Compared to the nationally reported prevalence of anxiety, depression and ADD, [hyperhidrosis] patients have a statistically significant higher prevalence than the general public. Providers should be aware of the increased prevalence of mental health disorders in patients with hyperhidrosis.”
