Thread: Need a plausible medical condition for my story

Does anyone know of a medical condition where you would be especially susceptible to losing consciousness from light blows to the head? I was looking at hypotension, or low blood pressure, but don't know if this would be it.

I am writing a scene in which my main character lightly injures the antagonist, in a way that would not normally be that serious, but since the antagonist has (insert condition here) it causes the antag to black out and fall to their death. I am trying to maintain ambiguity in whether or not the antag's death was directly the main character's fault or not.

Thanks!

When I think of loss of consciousness, I immediately think loss of balance control. So definitely neurological as well as hearing disorders come to play. Hmm... How about labyrinthitis? This is basically the inflammation of your inner ear, causing vertigo, as the ear is an organ for balance. There's also Meniere's Disease, and though it's exact cause is idiopathic, it is said to have come from the bursting of fluid sacs inside the ear. This sort of clogs the inner ear and causes the loss of balance.

As for damages to the brain, there's increased Intracranial Pressure. Basically any disease involving increased ICP subjects the patient to a risk in losing consciousness. Patients with ischemic stroke, perhaps? A light blow is enough to further increase that ICP and make the patient lose consciousness.

Loss of balance does not equal loss of consciousness. But with the inner ear issues the character would definitely be more prone to falling down with a light blow and hitting their head on the ground, perhaps, leading to bleeding into the brain structure and death. Fuhrer might be onto something here.

Try ...

"A reflex anoxic seizure is a type of fit triggered by a temporary cutting off of the supply of blood to the brain.
A reflex anoxic seizure can be induced by any unexpected stimuli such as pain, fear or fright, or even by a very hot or cold bath.
The trigger factor causes the heart to stop or slow down dramatically, which in turn reduces the flow of blood to the brain.

They are most common between the ages of six months and two years but they can also occur in teenagers and adults."

Or "A vasovagal syncope" which is similar and is the most common form of fainting in adults.

Thanks for the replies. All good suggestions.

But I'm thinking the inner ear thing might work best... the character who dies is a high school athlete, and it got me thinking that maybe earlier in the story, he could've experienced vertigo once or twice on the field. This would set a little bit of precedent for the cause of his accidental death later.
