How long after an accident can brain trauma symptoms appear? My relative had brain trauma from a car accident several decades ago, and is now showing signs of mental impairment. Can these symptoms be attributed to the past brain trauma?

In brief: Evaluation needed

There is some increased risk of later dementia in individuals with traumatic brain injury, especially if it was severe - but cognitive declines can be caused by age, metabolic conditions, depression or other factors.
New impairment warrants prompt neurological and neuropsychological assessment to assess the greater likelihood something recent is going on and figuring appropriate treatment.

In brief: As you

Are hearing with the late follow up in the nfl players there are definite concerns here.
Multiple events a big issue and one severe event probably raises concerns as well.

In brief: There

There is new information, primarily from the sports world, about a disease called chronic traumatic encephalopathy, which is due to repeated concussions causing brain breakdown later in life.
This is still not well understood. But this story sounds like a single injury, and probably would not be the same thing. Even if the injury was quite severe, it does not make sense that, decades later, their mental state would deteriorate. This person should be evaluated to see if there's something else going on to cause the deterioration. The most common thing, unfortunately, would be dementia from some other cause.
