Question

Define constructional apraxia and its symptoms. As well as the parietal region most associated with this type of apraxia.

a. Difficulty in dressing, left parietal lobe, inability to comprehend shapes.
b. Difficulty in drawing, right parietal lobe, inability to construct objects.
c. Difficulty in writing, frontal lobe, inability to read.
d. Difficulty in speaking, occipital lobe, inability to understand colors.

Answer 1

Constructional apraxia is a condition where individuals have difficulty in drawing or constructing objects due to damage in the right parietal lobe. It involves issues with spatial relationships and is related to the processing of sensory information and language.

Step-by-step explanation:

Constructional apraxia refers to a neuropsychological condition characterized by an individual's inability to draw, construct, or assemble objects, despite having the necessary motor skills to do so. This condition is typically associated with damage to the right parietal lobe of the brain. Symptoms include difficulty in drawing or constructing shapes and a failure to grasp spatial relationships, which makes everyday tasks such as dressing challenging.

Different types of aphasias are associated with damage to the Broca's or Wernicke's areas, which are integral to language function and are localized in the left hemisphere. There is also a relationship between language impairment and the ability to perform tasks requiring praxis and gnosis because of the cortical processing that involves integrating sensory information and language-dependent processing.
