: My 63 year old father was just diagnosed with a neurological disease
  called allodenia.  His doctors say that it developed from multiple
  mini-strokes.  I have looked everywhere for information on this, but
  I cannot find a thing.  Can you give me any information or sources
  of information on this disease?  Thank you.

Hello Allison,
The term allodynia simply is a descriptive term used to  describe a condition in which there is an abnormally excessive reaction to any stimuli.  For instance, patients who perceives a light touch as a painful sensation have allodynia.  In your fathers circumstance it is likely that this is caused by a mini-stoke in the region of the thalamus which is a midline structure in the brain.  The thalamus is a relay station for all the sensory impulses that go to the brain with the exception of olefaction (smells).  In  patients who have had a stroke in the region of the thalamus, their sensory function on one side of the body can become impaired.  With time this can problem can evolve into allodynia.  Medications such as amitriptyline, tegretol, pamelor, and neurontin have been used in order to treat this problem.
