🛑 Alien hand syndrome 👽👽 is a phenomenon in which one hand is not under control of the mind. The person loses control of his hand totally, and it acts as if it has a mind of its own. The etiology includes neurosurgery, aneurysms, tumor, and rarely stroke, so there should be brain damage.
🛑 CASE DESCRIPTION
A 60-year-old women with chronic atrial fibrillation had her anticoagulation stopped temporarily for spine surgery. No bridging with low-molecular-weight heparin was done. three days later, while watching television, she noted her right hand flinging across her visual field. Her right hand stroked her nose and hair without her will. She got terrified. Her attempts to control the left hand with the right hand were unsuccessful. She did not have any control of the left hand for almost 45 minutes as it continued to make purposeful movements. She later noted that her right upper limb was numb and slightly weak when she regained control. Her husband helped her to the car to take her to the hospital, and he noted that she was dragging her right leg while walking.
In the hospital, a computed tomography (CT) scan and magnetic resonance imaging (MRI) of the brain showed acute infarcts in both parietal lobes. Transthoracic and transesophageal echocardiograms did not show any evidence of thrombus. She gradually gained normal control of the left side over the next 6 hours. A diagnosis of stroke possibly due to cardioembolism was made. Her anticoagulation was resumed, and she was discharged home with advice to maintain anticoagulation at all times.
