Problematic Internet Use in Frontotemporal Dementia: A Case Series.

The present study investigated problematic internet use (PIU) among 61 patients with frontotemporal dementia (FTD) compared to a cohort of 354 patients with mild cognitive impairment (MCI) and Alzheimer's dementia. PIU was identified in 22.9% of FTD patients compared to only 0.8% of AD patients (p < 0.001). Behaviors included compulsive social media use, gaming, and online shopping. These findings suggest that PIU may represent an emerging behavioral feature associated with FTD, significantly more prevalent than in MCI and Alzheimer's dementia. Recognizing these digital behaviors could provide valuable clinical insights for diagnosis and management in the digital age.
