Memory impairment is another common effect associated with frontal lobe injuries, but this effect is less documented and may or may not be the result of flawed testing. [3] Damage to the frontal lobe can cause increased irritability, which may include a change in mood and an inability to regulate behavior. [1]
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production. Frontal lobe syndrome can be caused by a range of conditions including ...
The most frequent cause of the syndrome is brain damage to the frontal lobe. Brain damage leading to the dysexecutive pattern of symptoms can result from physical trauma such as a blow to the head or a stroke [6] or other internal trauma. It is important to note that frontal lobe damage is not the only cause of the syndrome.
Temporal lobe signs usually involve auditory sensation and memory, and may include: [citation needed] deafness without damage to the structures of the ear, described as cortical deafness; tinnitus, auditory hallucinations; loss of ability to comprehend music or language, described as a sensory aphasia (Wernicke's aphasia)
Signs and symptoms are classified into three groups based on the affected functions of the frontal and temporal lobes: [8] These are behavioural variant frontotemporal dementia, semantic dementia, and progressive nonfluent aphasia. An overlap between symptoms can occur as the disease progresses and spreads through the brain regions.
FTD is caused by shrinking in the frontal and temporal lobes of the brain, which control personality, behavior and language. ... “Most people, when they think of the word dementia, they think ...
Frontal lobe damage often disrupts this process, preventing the retrieval of information and the evaluation of its output. [ 21 ] [ 22 ] Furthermore, researchers argue that confabulation is a disorder resulting from failed "reality monitoring/source monitoring" (i.e. deciding whether a memory is based on an actual event or whether it is ...
Individuals with frontal lobe damage have deficits in temporal context memory; [6] source memory can also exhibit deficits in those with frontal lobe damage. [7] It appears that those with frontal lobe damage have difficulties with recency and other temporal judgements (e.g., placing events in the order they occurred), [8] and as such they are unable to properly attribute their knowledge to ...
