  2. Frontal lobe disorder - Wikipedia

    en.wikipedia.org/wiki/Frontal_lobe_disorder

    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.

  3. Focal neurologic signs - Wikipedia

    en.wikipedia.org/wiki/Focal_neurologic_signs

    Frontal lobe signs usually involve the motor system and may include many special types of deficit, depending on which part of the frontal lobe is affected: [citation needed] unsteady gait (unsteadiness in walking) muscular rigidity, resistance to passive movements of the limbs

  4. Brain tumor - Wikipedia

    en.wikipedia.org/wiki/Brain_tumor

    People may experience symptoms regardless of whether the tumor is benign (not cancerous) or cancerous. [13] Primary and secondary brain tumors present with similar symptoms, depending on the location, size, and rate of growth of the tumor. [14] For example, larger tumors in the frontal lobe can cause changes in the ability to think.

  5. Dysexecutive syndrome - Wikipedia

    en.wikipedia.org/wiki/Dysexecutive_syndrome

    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.

  6. Hypofrontality - Wikipedia

    en.wikipedia.org/wiki/Hypofrontality

    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.

  7. Frontotemporal lobar degeneration - Wikipedia

    en.wikipedia.org/wiki/Frontotemporal_lobar...

    Frontotemporal lobar degeneration; Neuropathologic analysis of brain tissue from FTLD-TDP patients. Ubiquitin immunohistochemistry in cases of familial FTLD-TDP demonstrates staining of (a) neurites and neuronal cytoplasmic inclusions in the superficial cerebral neocortex, (b) neuronal cytoplasmic inclusions in hippocampal dentate granule cells, and (c) neuronal intranuclear inclusions in the ...

  8. Anosodiaphoria - Wikipedia

    en.wikipedia.org/wiki/Anosodiaphoria

    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 ...

  9. Anosognosia - Wikipedia

    en.wikipedia.org/wiki/Anosognosia

    Anosognosia is a condition in which a person with a disability is cognitively unaware of having it due to an underlying physical condition. Anosognosia results from physiological damage to brain structures, typically to the parietal lobe or a diffuse lesion on the fronto-temporal-parietal area in the right hemisphere, [1] [2] [3] and is thus a neuropsychiatric disorder.
