This study will examine the factors that contribute to changes in swallowing as people age. Over the next ten years, researchers will follow healthy adults (age 18 and older) to see if swallowing becomes more difficult with age. They will also look at whether changes in the brain, thinking skills, and body chemistry are connected to swallowing problems. The information from this study may help doctors find ways to address problems such as choking or aspiration pneumonia in older adults.

Participants can change their mind and stop participating at any time, for any reason. Leaving the study will not affect any benefits or care they are entitled to.

The purpose of this study to help us understand if adding transcranial Direct Current
Stimulation (tDCS), a non-invasive brain stimulation technique, to Speech Therapy
improves language recovery in people with Broca's aphasia and is more effective than Speech Therapy alone.

To assess comparable efficacy of aphasia therapy administered via telerehab (aphasia remote therapy; ART) to aphasia therapy administered in clinic (in-clinic therapy; I-CT).
