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.
Wernicke encephalopathy (WE), also Wernicke's encephalopathy, [1] or wet brain is the presence of neurological symptoms caused by biochemical lesions of the central nervous system after exhaustion of B-vitamin reserves, in particular thiamine (vitamin B 1). [2]
The frontal lobe is thought to be the primary area for the lack of emotional insight seen in anosodiaphoria, such as in frontotemporal dementia. A recent 2011 study done by Mendez and Shapira found that people with frontotemporal dementia also had a loss of insight more properly described at "frontal anosodiaphoria", a lack of concern for ...
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]
Treatments can include, but are not limited to, rehabilitation therapy such as physical or occupational, pharmacological modification of the neurotransmitter function, or medication. [18] The affected parts of the brain can recover some function with the help of different types of therapy, or tractographical psysurgery.
- Medial temporal lobe atrophy (MTA) - Posterior atrophy (PA) - Frontal cortical atrophy (fGCA) CT and MRI are most commonly used to observe the brain for cerebral atrophy. A CT scan takes cross sectional images of the brain using X-rays, while an MRI uses a magnetic field. With both measures, multiple images can be compared to see if there is ...
Hypofrontality is a symptom of numerous neurological diseases defined as reduced utilization of glucose and blood flow in the prefrontal cortex. Hypofrontality can be difficult to detect under resting conditions, but under cognitive challenges, it has been seen to correlate with memory deficits along with executive function deficits.
Korsakoff psychosis typically follows after the symptoms of Wernicke's decrease. [29] [30] Wernicke-Korsakoff syndrome is typically caused by conditions causing thiamine deficiency, such as chronic heavy alcohol use or by conditions that affect nutritional absorption, including colon cancer, eating disorders and gastric bypass.
