Lesions in the temporal lobe may result in which type of agnosia?
A
Auditory
B
Visual
C
Tactile
D
v
Explanation: 

Detailed explanation-1: -Hearing (auditory agnosia): People cannot identify objects based on sound. For example, they cannot identify a telephone when they hear it ring. This type of agnosia results from damage to the temporal lobe. .

Detailed explanation-2: -Auditory agnosia is an inability to recognize sounds despite intact hearing. Auditory agnosias are typically associated with right side temporal lesions.

Detailed explanation-3: -Although auditory agnosia typically results from bilateral superior temporal lobe damage, it has also been reported following unilateral damage to the primary auditory cortex.

Detailed explanation-4: -Verbal auditory agnosia (also known as (pure) word deafness) refers to deficits specific to speech processing, environmental sound agnosia refers to difficulties confined to non-speech environmental sounds, and amusia refers to deficits confined to music.

Detailed explanation-5: -However, auditory agnosia has also been reported following unilateral damage to the primary auditory cortex, although it typically caused by damage of the bilateral superior temporal lobe. In our case, it is also likely that traumatic ICH in the left temporal lobe is thought as a major cause of verbal auditory agnosia.
