Alien Hand Syndrome

Alien hand syndrome as the presentation of cardioembolic stroke is extremely rare but can be terrifying to patients. [semanticscholar.org]

The AVF subtype presents with the disinhibited groping and reaching for objects that are within arms reach without the patients will or control. [ausmed.com]

This case is presented to create awareness of this interesting clinical scenario, which can be terrifying to the patients and confusing to the physicians who are not aware of it. [ncbi.nlm.nih.gov]

  • Unconsciousness

    Thus, we argue that both precuneus as well as the IFG may reflect conflicts of agency in unconscious and unwanted movements. However, other explanations may also account for the activation of the right IFG. [journals.plos.org]

    The mildest form of the syndrome is caused by damage to the brain’s parietal and/or occipital lobe, causing a hand to unconsciously avoid contact with objects by “levitating” with its fingers extended. [damninteresting.com]

    It is rare but significant due to its disability impact on everyday life. This case highlights the clinical features, recovery course and response to rehabilitation of a patient with a dominant anterior cerebral artery territory infarct. Methods .  [tandfonline.com]

  • Dysphagia

    Clinical signs and symptoms included right hemiparesis, hemianesthesia, dysphagia, language and cognitive dysfunction, personification and autonomous movement of the affected limb; involuntary grasping of objects interfered with his activities of daily [tandfonline.com]

  • Hemianesthesia

    Clinical signs and symptoms included right hemiparesis, hemianesthesia, dysphagia, language and cognitive dysfunction, personification and autonomous movement of the affected limb; involuntary grasping of objects interfered with his activities of daily [tandfonline.com]

    Of these two disturbances, the former is better termed “somatoparaphrenia” ( Joynt and Goldstein 1975 ) or “asomatognosia” ( Thomas et al 1998 ) and is usually associated with hemianesthesia. [medlink.com]

  • Abnormal Involuntary Movement

    Alien hand syndrome has been reported to be associated with several abnormal involuntary movements when different regions of the brain, like the corpus callosum, parietal region, or frontal region, are involved. [ncbi.nlm.nih.gov]

  • Tonic Posturing

    Thus, "alien hand" has been extended to include non-goal-directed, involuntary tonic posturing ( Bundick and Spinella 2000 ; Inzelberg et al 2000 ; Sabrie et al 2015 ), even though the patient may not indicate any sort of alien quality ( Ball et al 1993 [medlink.com]

  • Convulsions

    The affected hand is not weak but maintains normal strength, and the hand movements are not spastic or convulsive. [ptproductsonline.com]

Over the course of 4 months the rehabilitation treatment targeted toward the specific needs of the patient, allowed improvement in his ADL. [tandfonline.com]

There is currently no treatment for alien hand syndrome. All a patient can do to control the problem is to keep the hand busy by having it hold an object. [medicinenet.com]

Prognosis of CBD is poor with a mean survival of only 7 years[ 5 ]. Parkinsonism generally responds poorly to dopaminergic medication. The main emphasis of management is supportive with a multidisciplinary team approach. [academic.oup.com]
