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 ...
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]
Symptoms of a mild brain injury include headaches, confusions, tinnitus, fatigue, changes in sleep patterns, mood or behavior. Other symptoms include trouble with memory, concentration, attention or thinking. [3] Mental fatigue is a common debilitating experience and may not be linked by the patient to the original (minor) incident.
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 ...
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.
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.
Perforating injuries have an even worse prognosis. [2] Penetrating head trauma can cause impairment or loss of abilities controlled by parts of the brain that are damaged. A famous example is Phineas Gage, whose personality appears to have changed (though not as dramatically as usually described) after a perforating injury to his frontal lobe(s).
The frontal lobe is responsible for problem solving, motor function, memory, judgment, impulse control, and social behavior. It is also needed for goal-directed behavior. Patients with frontal lobe injury may have problems in the selection, production, and organization of goal-directed behavior. [5]
