Nearly 50% of adult persons living with HIV (PLWH) experience HIV-associated neurocognitive disorder (HAND), which is associated with deteriorating brain health and cognitive functioning. Multimodal interventions that simultaneously improve physical activity, nutrition, and sleep hygiene may be of value for adult PLWH, especially as they age and become vulnerable to HAND. We used four focus groups of PLWH (N = 30; ages ≥ 50 years) to solicit feedback about Cognitive Prescriptions, a multimodal cognitive intervention. Lifestyle and health behaviors pertaining to Cognitive Prescriptions were assessed, including: (a) physical activity, (b) mental activity, (c) nutrition, (d) social engagement, (e) emotional health, (f) sleep hygiene, and (g) substance use. When presented a template of the intervention, participants expressed favorable opinions and remarked they would want to work with a clinician, paraprofessional, or peer to implement such a program into their own daily routines. From this, implications for practice and research are provided.
