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.
Those patients with a mild traumatic brain injury with frontal lobe damage seem to be only slightly affected, if affected at all. Frontal lobe injuries have been shown to cause decreased ability in combining events that are temporally separated (separated by time), as well as recalling information in its correct context.
Research shows that the most common areas to have focal lesions in non-penetrating traumatic brain injury are the orbitofrontal cortex (the lower surface of the frontal lobes) and the anterior temporal lobes, areas that are involved in social behavior, emotion regulation, olfaction, and decision-making, hence the common social/emotional and ...
Frontal release signs are seen in disorders that affect the frontal lobes, such as dementias, metabolic encephalopathies, closed head injuries, and hydrocephalus. All of these disorders produce diffuse cerebral damage, usually involving many areas and systems in addition to the frontal lobes and pyramidal system , so the frontal release signs ...
Neurological imaging has shown that TMoA is typically caused by an infarct of the anterior superior frontal lobe in the perisylvian area [6] of the left, or language-dominant, hemisphere. [1] The anterior superior frontal lobe is known as the prefrontal cortex which is responsible for the initiation and ideation of verbal speech. [7]

Cerebral contusion is bruising of the brain tissue. The piamater is not breached in contusion in contrary to lacerations. The majority of contusions occur in the frontal and temporal lobes. Complications may include cerebral edema and transtentorial herniation. The goal of treatment should be to treat the increased intracranial pressure. The ...
Tongue thrusting and speech problems may co-occur. Due to unconventional postures of the tongue and other articulators, interdental and frontal lisping are very common. The alveolar sounds /s/ and /z/ are produced more anteriorly thus leading to interdental fricative like sounds, /th/. [4]
