Is it bad that right after i jog 25 minutes every other night, ill try an remember everywhere i jogged but i never can! i'm 18, grandma had dementia?

At age 18 I don't : Believe you have dementia. When i was a distance runner, i would get into a particular mind set and often was inattentive to my surroundings for miles. Kind of like driving without really being fully aware until you realize that your drove past your exit. *** by the way, see that you suffer from insomnia. If you run late in the evening that may be contributing to your sleep difficulties.***.

No dementia: I would recommend seeing a sleep specialist who is either a psychiatrist or a neurologist and who can gather more history. It is possible you are too self-absorbed to recall, you are sleep deprived, or your sleep apnea is not well controlled. Dissociation of a more complex type is a more remote possibility but needs to be checked out.Best wishes. I hope next time you can jog your memory more.
