Somatoparaphrenia

Somatoparaphrenia is commonly found in the (a)   hemisphere of the brain and affects the ​ (b)   side of the body

• right
• same
• opposite
• left
• middle
• anterior
• posterior

Answer explanation

Although damage to the left hemisphere of the brain can produce the same symptoms, it is more common for lesions on the right side of the brain to produce this condition

​ ​ (a)   is regarded as a possible risk factor for Somatoparaphrenia

• Blood Vessel Disease
• Broken Bones
• Cancer
• Brain Lesions

Answer explanation

Other risk factors include:

• - Stroke

  • - Traumatic Brain Injuries

  • - Neurological Disorders (such as Alzheimer's)

  • - Sensory impairments

  • - Hemispatial neglect

  • - Executive dysfunction

  • - Memory disorders

Identify the neuroanatomical markers for this condition?

Answer explanation

Neuroanatomical Marker:

• - Thalamus & Basal Ganglia

• - Lesions on the temporoparietal junction and orbitofrontal cortex

• - Damage to Post Central Gyrus, right-side hippocampus, and amygdala

• - Internal Capsule

• - Corona Radiata

• - Superior Longitudinal Fasciculus

​ (a)   is characterised by the denial of one's condition.

• Anosognosia
• Misoplegia
• Asomatognosia
• Phantom Limb

Answer explanation

Anosognosia is a broader condition involving a lack of awareness or denial of one's own illness or deficits, while asomatognosia is a specific form of body-awareness disorder where a person has impaired awareness or recognition of specific body parts.

Misoplegia - the morbid hate of one's own body part

Phantom Limb - experiencing sensations or pain in a limb that does not exist

​ (a)   is used to manipulate the visual perspective of an individual's hand?

• Visual-Spatial Test

• Rubber-Arm Illusion

• Proprioceptive Manipulation

• Rubber-Hand illusion

Answer explanation

This test uses a board to block the direct perception of one of their hands and uses a rubber hand as replacement. The brain is tricked to thinking that it is one's own hand, even to the point of stimulating pain when hit!

Also, viewing the hand via a mirror significantly increased ownership, in regards to patients with somatoparaphrenia (Jenkinson et al., 2013)
