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. [14]
Frontal lobe syndrome can be caused by a range of conditions including head trauma, tumours, neurodegenerative diseases, neurodevelopmental disorders, neurosurgery and cerebrovascular disease. Frontal lobe impairment can be detected by recognition of typical signs and symptoms, use of simple screening tests, and specialist neurological testing.
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.
Alzheimer’s UK says that FTD symptoms are “very different” to other more common types of dementia, such as day-to-day memory loss – adding that in the early stages of the disease, many ...
The PA news agency takes a closer look at the disease, also known as FTD
The frontal lobe is responsible for things like decision-making, judgement, movement, speaking, self-control and social skills, and the temporal lobes are responsible for hearing, understanding ...
Frontal release signs are primitive reflexes traditionally held to be a sign of disorders that affect the frontal lobes. The appearance of such signs reflects the area of brain dysfunction rather than a specific disorder which may be diffuse, such as a dementia, or localised, such as a tumor. [1] One reflex thought to have good localizing value ...
The inferior frontal gyrus is the specific part of the frontal lobe [9] responsible for generating stop processes. [10] [11] [12] Hence, when a patient experiences frontal lobe dysfunction, the inferior frontal gyrus is impacted, resulting in movement perseveration (an abnormal prolongation of current activity), [13] and appearance of the ...
