Allochiria
Allochiria
Allochiria (pronounced: al-oh-ki-ree-uh) is a neurological disorder characterized by the mislocation of sensory stimuli. It is often associated with conditions such as stroke and migraine.
Etymology
The term 'Allochiria' is derived from the Greek words 'allos', meaning 'other', and 'cheir', meaning 'hand'. This refers to the condition's characteristic symptom of perceiving a stimulus applied to one side of the body on the opposite side.
Symptoms
The primary symptom of Allochiria is the misperception of sensory stimuli. For example, a person with this condition may feel a touch on the left hand as a touch on the right hand. This can occur with any sensory modality, including touch, pain, temperature, and proprioception.
Causes
Allochiria is most commonly caused by lesions in the parietal lobe of the brain, particularly in the right hemisphere. It can also be caused by damage to the thalamus or cerebral cortex. It is often seen in patients who have had a stroke or who suffer from migraines.
Treatment
Treatment for Allochiria primarily involves managing the underlying condition that is causing the symptoms. This may involve medication, physical therapy, or in some cases, surgery.
