That's a really interesting observation. The short answer is that your brain's sensitivity to triggers like flashing lights and patterns isn't constant — it shifts throughout the day based on your body's internal clock, known as your circadian rhythm.

Research has shown that circadian rhythms actually regulate how likely a seizure is to occur. This means there are certain windows of the day when the brain is more vulnerable, making triggers like visual stimuli more likely to set off seizure activity.

Studies have found that seizure peaks tend to cluster around:

- 8 a.m.
- 8 p.m.

So if flashing lights or patterns seem more problematic at certain times, it may align with these natural vulnerability windows. Other factors can also raise sensitivity at certain times of day, including:

- Sleep deprivation — being tired, especially in the morning, is one of the most common seizure triggers
- Stress levels, which tend to fluctuate throughout the day
- Medication timing — seizure medications may actually be more or less effective at different times depending on how the body processes them

It's worth keeping a seizure diary to track when visual triggers seem worse. Sharing those patterns with a neurologist could help fine-tune a management plan.
