This type of condition is considered rare 2, although lesions to the parietal lobe aren’t. If untreatable some ways they may overcome their obstacles may include rehab where a combination of physical and mental exercises are used to help alleviate symptoms 4. Although in other cases treatment is possible with antiepileptic drugs, which have been known to remedy symptoms within a few days 1. Sacks was whether or not the patient was treatable. If the corticospinal tract starts on the right side of the brain it will decussate (cross over) in the myelencephalon to the opposite side of the body where it is connected to the spinal cord and then to the left leg 3. The corticospinal tract is commonly affected since the axons between the cerebral cortex and spinal cord cannot correctly integrate or transmit information 1. The parietal lobe is responsible for the spatial awareness of your body, as well as many sensory inputs to the brain such your sense of touch 1. Sacks did not diagnose what part of the brain was responsible for causing the symptoms but after some research, it has been attributed to damage to the right parietal lobe 1. This is typical of the neurological disorder parietal ataxic hemiparesis 1. The patient’s symptoms initially consisted of weakness in his left leg but grew to a more serious condition where there was complete loss of sensation in his left leg. When the neurologist arrived to see what was taking place, he soon realized this man had been talking about his own leg. Quickly he realized it was attached to him and fell from bed along with the estranged leg.
With a feeling of disgust, he tried to physically remove the strange leg from his bed. After falling asleep, the man awoke and found what he thought to be a cadaver’s left leg in bed with him. In this story, a man was admitted to the hospital for exhibiting signs of a “lazy left leg”.
