Home-based Brain Stimulation Treatment for Post-acute Sequelae of COVID-19 (PASC)

Home-based Transcranial Direct Current Stimulation (tDCS) for Treatment of Cognitive Post-acute Sequelae of COVID-19 (PASC)

The main goal of this study is to improve dysexecutive symptoms (e.g., sustained attention, processing speed) in patients exhibiting post-acute sequelae of COVID-19 (PASC) through home-based transcranial direct current stimulation (tDCS), a noninvasive method that uses low intensity electric currents delivered to the brain through stimulation electrodes on the scalp.

Inclusion Criteria:

• Ability to provide informed consent
• A diagnosis of PASC as indicated by past COVID-19 infection, and persistent symptoms, including 'brain fog', confusion, short-term memory deficits, trouble concentrating, delirium, difficulties in multitasking.

Exclusion Criteria:

• History of epilepsy
• Metallic implants in the head and neck,
• Brain stimulators
• Pacemakers
• Pregnancy
• Active substance dependence (except for tobacco)
• Premorbid major neurological illness
• Severe mental illness (e.g., bipolar disorder, schizophrenia)
• Attention Deficit Hyperactivity Disorder
