Dear Mr. Yuan,
Thank you for reaching out with your concerns regarding your father's sudden memory loss. This is indeed a complex issue that many families face as their loved ones age. Let’s address your questions one by one.

1. Is this a precursor to dementia?
The symptoms you describe, such as repeatedly asking the same questions, can indeed be indicative of early signs of dementia, particularly if this behavior is new and not typical for your father. This condition is often referred to as "short-term memory loss" or "repetitive questioning," which can be alarming for families. However, it is important to note that not all memory loss is due to dementia. Conditions such as stress, anxiety, depression, or even sleep disturbances can also lead to similar symptoms.
2. Why does this happen suddenly rather than gradually?
Sudden changes in memory can occur for several reasons. One possibility is a transient ischemic attack (TIA), often called a "mini-stroke," which can temporarily affect cognitive function. Other factors could include medication side effects, dehydration, or even infections, which are more common in older adults. Additionally, psychological factors such as anxiety or depression can manifest as sudden memory issues. It’s crucial to have a thorough medical evaluation to determine the underlying cause.

3. If it is a precursor to dementia, can seeking treatment prevent further deterioration?
Early intervention is key in managing cognitive decline. If your father is diagnosed with a form of dementia, there are treatments available that can help manage symptoms and potentially slow the progression of the disease. Medications such as cholinesterase inhibitors are commonly prescribed for Alzheimer’s disease, which is the most prevalent form of dementia. Furthermore, lifestyle changes, cognitive therapies, and supportive care can also play a significant role in maintaining quality of life.

4. Which department should I consult for this condition, and are there renowned doctors in the southern region?
For memory-related issues, you should consult a neurologist or a geriatrician. These specialists are trained to assess cognitive function and diagnose conditions like dementia. In southern Taiwan, you might consider hospitals such as Kaohsiung Medical University Hospital or Tainan Municipal Hospital, which have departments specializing in neurology and geriatrics. It’s advisable to look for doctors who have experience in dementia care, as they will be more familiar with the latest diagnostic tools and treatment options.

In conclusion, I recommend that you seek a comprehensive evaluation for your father as soon as possible. This will help determine the cause of his memory issues and allow for timely intervention if necessary. It’s understandable to feel anxious about these changes, but remember that many conditions are treatable or manageable with the right care.
Wishing you and your family the best during this challenging time. Please take care.

Sincerely,
