Traumatic brain injury, hit by an engine. Patient briefly had mania and epilepsy followed by dementia; portion of frontal and parietal bone removed. Most patients with severe TBI who recover consciousness experience cognitive disabilities, including the loss of many higher-level mental skills.
The causes of frontal lobe disorders can be closed head injury. An example of this can be from an accident, which can cause damage to the orbitofrontal cortex area of the brain. [2] Cerebrovascular disease may cause a stroke in the frontal lobe. Tumours such as meningiomas may present with a frontal lobe syndrome. [11]
Injuries to the frontal lobe and/or the basal ganglia can interfere with an individual's ability to initiate speech, movement, and social interaction. Studies have shown that 5-67% of all patients with traumatic brain injuries and 13% of patients with lesions on their basal ganglia experience some form of diminished motivation. [2]
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.
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.
Witzelsucht can occur in the context of frontotemporal dementia, a neurological disorder resulting from degeneration of the frontal lobes and/or anterior temporal lobes. There are a range of neuropsychiatric symptoms associated with frontal lobe dementia, including progressive declines in social conduct, insight, and personal and emotional ...
Confabulation can occur with nervous system injuries or illnesses, including Korsakoff's syndrome, Alzheimer's disease, schizophrenia, and traumatic brain injury. It is believed that the right frontal lobe of the brain is damaged, causing false memories. Children are especially susceptible to forced confabulation as they are highly impressionable.
Nearly 20% of the more than 2.5 million U.S. service members (SMs) deployed since 2003 to Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) have sustained at least one traumatic brain injury (TBI), predominantly mild TBI (mTBI), [90] [91] and almost 8% of all OEF/OIF Veterans demonstrate persistent post-TBI symptoms more than ...
