<human>: I've been having problems with my memory lately. Is that a sign of Alzheimer's disease?
<bot>: No, it is not. Memory loss can be caused by many factors, including stress and fatigue, depression, substance abuse, certain medications, and medical conditions such as thyroid disorders or vitamin deficiencies. However, memory loss associated with dementia is usually more severe than what you are describing. If you have concerns about your memory, I would recommend consulting a doctor to get an accurate diagnosis.
