Loss of episodic memory
My grandmother suddenly asked about some things related to my grandfather last night, but those events happened a long time ago.
She seems to have forgotten about my grandfather's current situation and only remembers past events about him.
However, this memory loss appears to be limited to just that specific segment; everything else seems normal.
The day before this incident, I remember my grandmother telling me that she felt sorry for my grandfather (who has Parkinson's disease) because he was not sleeping well that day, which affected his condition.
She mentioned that seeing him like that made her so sad that she couldn't sleep, and she kept thinking about it.
As a result, the next day, she could only recall memories of my grandfather from the past.

Hello: If neurological symptoms occur for a very short duration, it may be necessary to consider cerebrovascular diseases (such as stroke or hemorrhage affecting memory areas).
However, it could also be transient global amnesia, which is often associated with changes in blood flow or metabolism in specific areas near the hippocampus, which is responsible for memory.
The medical community has not reached a consensus on the underlying causes, but general emotional changes or significant temperature fluctuations, such as swimming in cold water or taking very hot baths, may trigger the condition.
During an episode, patients may feel disoriented, repeatedly ask the same questions, or even be unaware of their location and forget their names.
The amnesia can onset rapidly and recover suddenly; patients typically have no recollection of events that occurred during the amnesic period, but recovery usually happens within 24 hours.
The incidence is higher in individuals aged 60 to 65, and it can affect both men and women.
If sudden amnesia occurs, it is advisable to seek emergency medical care for a CT scan or blood tests, as other causes such as medications, hypoglycemia, stroke, seizures, or even brain tumors can produce similar symptoms.
If there are concerns about declining memory, a comprehensive diagnosis and evaluation at a hospital is also recommended.
It is suggested that you consult a neurologist for discussion and treatment.
Wishing you good health and peace.
Sincerely, the Neurology Department.

Fragmented memory loss, particularly in the context of neurological conditions, can be a complex issue that often requires careful evaluation and understanding. In your grandmother's case, it seems she is experiencing a specific type of memory disruption that may be influenced by emotional stress and underlying neurological conditions, such as your grandfather's Parkinson's disease.
Memory loss can manifest in various forms, including anterograde amnesia (difficulty forming new memories) and retrograde amnesia (loss of memories from the past). In your grandmother's situation, it appears she is experiencing a form of retrograde amnesia, where she recalls events from the past but struggles to remember more recent occurrences. This can sometimes be triggered by emotional distress, particularly when a loved one is facing health challenges.
The emotional state of an individual can significantly impact cognitive function. Stress, anxiety, and depression can all contribute to memory issues. In your grandmother's case, her feelings of sadness and concern for your grandfather's well-being may have led to a temporary disruption in her memory processing. When individuals are preoccupied with emotional stress, their cognitive resources may become strained, leading to difficulties in recalling recent events or information.
Additionally, the presence of Parkinson's disease in your grandfather could also play a role in your grandmother's memory issues. Parkinson's disease is a neurodegenerative disorder that affects movement and can also impact cognitive functions, including memory. The stress of caring for someone with a chronic illness can lead to caregiver fatigue, which may further exacerbate cognitive difficulties in the caregiver, in this case, your grandmother.
To address your grandmother's fragmented memory loss, it may be beneficial to take several steps:
1. Encourage Open Communication: Talk to your grandmother about her feelings and concerns regarding your grandfather's health. Providing a supportive environment can help alleviate some of her emotional stress.
2. Memory Aids: Utilize memory aids such as photographs, journals, or videos that can help trigger memories of recent events. This can be particularly effective in helping her reconnect with more recent experiences.
3. Routine and Structure: Establishing a daily routine can help reinforce memory retention. Consistent schedules can provide a sense of stability and predictability, which may reduce anxiety and improve cognitive function.
4. Professional Evaluation: If the memory issues persist or worsen, it may be wise to consult a healthcare professional, such as a neurologist or geriatrician. They can conduct a thorough assessment to rule out any underlying neurological conditions and provide appropriate interventions.
5. Cognitive Exercises: Engaging in cognitive exercises, such as puzzles, memory games, or even simple storytelling, can help stimulate brain function and improve memory retention.
6. Monitor Sleep Quality: Since sleep plays a crucial role in memory consolidation, ensuring that your grandmother is getting adequate rest is essential. Poor sleep can exacerbate memory issues, so addressing any sleep disturbances is important.
In summary, fragmented memory loss can be influenced by a variety of factors, including emotional stress and underlying neurological conditions. By providing support, utilizing memory aids, and seeking professional guidance if necessary, you can help your grandmother navigate this challenging situation and potentially improve her memory function.
