Rare Neurological Condition: Elderly Woman Mistakenly Believes in Ghost Possession
An elderly woman experienced an unsettling episode, initially attributing her symptoms to supernatural causes. She observed her own arm moving autonomously, leading her to believe she was possessed. However, medical professionals later diagnosed her with an extremely rare condition. This case highlights the importance of seeking medical evaluation for unusual physical manifestations.
Unexplained Limb Movement Triggers Fear
The 77-year-old patient was at home watching television when she suddenly noticed her left hand moving involuntarily. According to a medical report, the hand began to stroke her face and hair without her conscious command.
Alarmed by this lack of control, she attempted to use her right hand to restrain the errant left hand. Despite her efforts, she was unable to stop the autonomous movements and was forced to observe her hand acting independently for approximately 30 minutes.
Hospital Evaluation and Initial Stroke Suspicion
Concerned, the woman’s husband immediately took her to the hospital. He reported to the medical staff that his wife had been dragging her left leg while walking, in addition to the uncontrolled hand movement.
Considering the symptoms, doctors at the hospital suspected a neurological issue, possibly involving a stroke. They promptly ordered a CT scan and an MRI to examine her brain.
Diagnosis: Parietal Lobe Stroke and Alien Hand Syndrome
The brain scans revealed the presence of ‘acute infarcts in both parietal lobes’. These infarcts indicated strokes had occurred in the parietal lobes, regions of the brain situated behind the frontal lobe. A parietal lobe stroke can disrupt blood supply to this brain area, potentially resulting in various neurological deficits. These can include loss of motor control, language difficulties, reading impairments, behavioral changes, and visual disturbances.
As the elderly woman gradually regained voluntary control of her left side over a six-hour period, doctors reached a diagnosis of Alien Hand Syndrome (AHS). This rare neurological condition explains the involuntary limb movement she experienced.
Understanding Alien Hand Syndrome (AHS)
Alien Hand Syndrome, sometimes referred to as Dr. Strangelove syndrome, is a peculiar disorder where an individual’s hand, or in some cases hands, moves without conscious control. It often affects the left hand, which performs actions unbeknownst to the patient.
Due to these independent actions, individuals with AHS may feel detached from the affected limb, as if it is controlled by an external force. Sensation in the alien hand may also be diminished, leading to a reduced ability to feel touch.
Case Study Details and Potential Causes
Doctors who examined the case in 2014 described Alien Hand Syndrome as a situation where a person loses command over their hand, causing it to act autonomously. They noted that the alien hand might grasp objects involuntarily, requiring the person to use their other limb to release them. In extreme instances, there have been reports of the alien hand even posing a threat of self-harm.
In this particular case, medical professionals speculated that the woman’s AHS may have been triggered by a stroke in the parietal lobes. This could be linked to her decision to discontinue her blood clot medication prior to planned spinal surgery.
The physicians emphasized that AHS resulting from a stroke is an uncommon occurrence, yet it can be a frightening experience for patients. Furthermore, they highlighted the exceptionally short duration of the alien hand episode in this woman’s case (30 minutes), making it the briefest instance of this phenomenon documented.
Duration and Diagnostic Insights
Typically, Alien Hand Syndrome can persist for days or even years, according to medical literature. In exploring potential cardiac contributions to her condition, doctors conducted an ultrasound of her heart to assess its structure and check for blood clots.
The results of the cardiac ultrasound indicated no heart-related issues, and her blood vessels were clear of clots. While the report doesn’t specify other diagnostic procedures, it acknowledges that there are no definitive tests specifically designed to diagnose AHS.
Recovery and Post-Diagnosis Instructions
Over the subsequent six hours, the elderly woman fully regained command of the left side of her body. She reported residual numbness and slight weakness in her left upper limb. Doctors advised her to resume her blood clot medication. She was discharged home without any lasting symptoms or further complications.
Rarity and Potential Triggers of AHS
Alien Hand Syndrome can arise from various underlying conditions, physical trauma, or as a consequence of certain brain surgeries. Currently, there is no established cure for AHS. Due to its infrequency, the precise number of individuals affected by AHS remains unclear. A medical literature review conducted in 2013 identified only approximately 150 documented cases.
