@dtbic2024 I am so very sorry for the loss of your Mom and the continued vascular cognitive decline of your Dad. Kudos to you and your sister for being such compassionate and committed caregivers. It must be so exhausting to watch his ongoing grief and emotional dysregulation, which is a symptom that comes with a history of strokes, MCI, progressing toward vascular dementia. In addition to being my husband’s caregiver, I am a licensed therapist and have completed many assessments of individuals with cognitive impairment and dementia. Your Dad’s current med for depression and/ or dose should be reevaluated, particularly because geriatric patients metabolize meds differently and usually have other conditions, and meds, to consider. He would benefit from a current evaluation also from a neurologist and you may want to research “psuedobulbar affect,” as well. Best wishes that you are able to get some answers and some relief from his current level of emotional distress.
