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]
Phineas P. Gage (1823–1860) was an American railroad construction foreman remembered for his improbable: 19 survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his life—effects sufficiently ...
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 ...
frontal lobe lesions: difficulty moving feet in contact with floor, tendency to fall backwards Bruns nystagmus: Ludwig Bruns: neurology: cerebellopontine angle tumor, vestibular schwannoma: nystagmus that coarsens in amplitude on lateral gaze Brushfield spots: Thomas Brushfield: ophthalmology, genetics: Downs' syndrome or non-pathological
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.
Railway spine was a nineteenth-century diagnosis for the post-traumatic symptoms of passengers involved in railroad accidents. The first full-length medical study of the condition was John Eric Erichsen's classic book, On Railway and Other Injuries of the Nervous System. [1] For this reason, railway spine is often known as Erichsen's disease.
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.
Focal neurologic signs, also known as focal neurological deficits or focal CNS signs, are impairments of nerve, spinal cord, or brain function that affects a specific region of the body, e.g. weakness in the left arm, the right leg, paresis, or plegia.
