topographical amnesia

we do not have exact datas on the frequency of the actual manifestation of the so called topographical amnesia-let this medical term exist here- in our lives. but first we need to exempify or make it more concrete what this term means. an example that i happened to experience- im terrible sorry for the inappropriate example :

for ages, we have our toiletchain on one side-that is on the right side,but somehow i can mix the sides up sometimes.we might have experienced the same or almost the same incongruous movements.

as it turned out, this strange mental disorder has been registered within medical circles as transient topograhical amnesia.

although, this state of mind is transitory, it might suggest the inclination to Alzheimer's Disease,or doesn't it?

transient topograhical amnesia appears in fiction. i would ,hereby, reflect upon the case of Raggle Gumm's example in Philip K. Dick's Time Out Of Joint.
