Memory loss to that degree is not generally a component of CH. I cannot speak for others, but I’ve certainly never had this problem. Have you/he discussed this with his Neurologist? They may want to see a fresh MRI/MRA to rule out dangerous stuff - again, depending upon the severity.

Is it possible that it’s more like being totally absorbed in the pain? That I could see!

I do get memory loss, but i have other kinds of headaches too that may contribute.  Also, I had what I thought was vertigo but it was just a surging feeling in my temple, not true vertigo.

Most docs & neuros want to do tests to eliminate other conditions that could be life threatening.  It is better to err on the side of caution here.

Good luck.

the only memory loss i get was form the topamax and gabapetin

I'm not sure what meds he's taking, but sometimes the meds can cause some memory loss (usually short term) topamax is known for this.

I do have a lot of memory loss, but then again I'm OLD and just blame it on that. I use a lot of post it notes (seriously). He might try that. It's worked for me for years.

A CAT or MRI might not be a bad idea, but check the meds first. It may be something that simple.

Any memory loss longer than a day or two may be either medication related and/or needs doc's attention.

[Edited for length.] In neuropsychologic evaluations, a reversible decline of memory processing was detected during the cluster attack, but not between two attacks. Long-term observation revealed no progressive cognitive decline in cluster headache patients over the years. With regard to personality changes, a liability susceptibility to anxiety disorders and to hypochondriasis, but not to mood changes, has been described inconsistently. All changes in alterations of cognitive processing in cluster headache are demonstrated to be mild and do not relevantly contribute to the clinical picture of this disease.

If memory loss is severe or a marked change you need to rule out an organic reason first.

Memory is by and large a process of association coupled with selective attention. I.e you select out what you dont need. This is different for everyone. For example a person who is deaf will have difficulty in selecting sounds.

During Ch attacks the pain is such that focus is usually complete on the intensity and the amelioration. It follows that you are not likely to select too much going on around you at that time. It does not affect selection and association inbetween hits or in times of remission.

You need a medical evaluation as soon as you can.

I hope you get some helpful answers and he gets freedom from pain.

Best wishes,
