Since my childhood, I have had difficulty in determining which side is left and which side is right. I had to resort to the scar on my left arm to determine the left-hand side.
Even now, I always get confused in directions, i.e., I am not good at finding directions (North, South, East, West) while driving.
Also, I am not good at signs in mathematics. Even though I get the equations mostly right, I get confused with + or -, especially in finance in which I cannot figure out spend or receive if there are negative red or black numbers.
Moreover, I get confused with positive or negative in chemistry. I am still not sure if cation is a positive ion or anion is a positive ion in electrochemistry.
Battery is even worse because there are abstract concepts like a + pole and a - pole, a positive charge and a negative charge, and they are opposite depending on whether you are talking about the electrical circuit external to the battery or internal chemistry.
In sports, I sometimes get confused which team is shooting left or right in a hockey game, for example.
In law, I often confuse which arguments were made by the plaintiff or the defendant in a legal document.
The list is endless, as it is not confined to topological geography but more general in nature. This symptom is different from dyslexia, as I have absolutely no problem with distinguishing between "b" and "d".
My quick scan of DSM-IV did not reveal anything, probably because the symptom does not significantly lower the quality of life? However, it should be an interesting topic in the quest to decipher the inner working of human brains.
Curiously, my Russian fiancé has exactly the same difficulty in terms of directions. So, if this disorder is still undefined, I propose that it be called "Sunatori-Musikhina Syndrome", please.
