Why is my 78 year old husband becoming aggressive?

Aggression in older adults can stem from various factors, including cognitive decline, such as dementia or Alzheimer's disease, which can affect behavior and emotional regulation. Physical health issues, pain, or discomfort may also contribute to irritability. Additionally, changes in routine, isolation, or frustration with limitations can lead to aggressive outbursts. It's essential to consult with a healthcare professional for a thorough evaluation and appropriate support.
