Study Notes
Frontal Lobe Syndromes
- Disinhibition, Impulsivity, Emotional Lability, Hyperkinesis are common behavioral symptoms related to frontal lobe damage.
- Pseudodepression with depressive symptoms can occur due to left frontal damage.
- Dorsomedial PFC is involved in motivation and initiation of activity, and damage can lead to akinesia, mutism, and apathy.
- Dorsolateral PFC plays a role in executive function, working memory, and attention. Damage results in deficits in these areas, as well as inattention, abulia.
- Phineas Gage suffered a dramatic personality change after frontal lobe damage, highlighting the crucial role of this lobe in personality and behavior.
- Frontotemporal Dementia is a neurodegenerative disease that affects the frontal and temporal lobes, leading to changes in personality, behavior, emotions, and language.
- Frontal Lobe Epilepsy manifests with unusual behavioral or motor manifestations, potentially mistaken for psychogenic events.
- Broca's Aphasia affects speech fluency, writing, and language production, but comprehension is generally preserved.
Parietal Lobe Anatomy and Syndromes
- The parietal lobe contains the primary sensory cortex and integrates functions like visual, auditory, and somatosensory information.
- The postcentral gyrus is the primary sensory cortex, responsible for processing sensory information from the body.
- The superior and inferior parietal lobules, including the supramarginal and angular gyrus, are involved in higher-order cognitive functions.
- The right parietal lobe is responsible for spatial attention, spatial relationships, and body awareness. Damage leads to hemineglect, constructional apraxia, dressing apraxia, and topographic disorientation.
- The left parietal lobe is involved in calculation, praxis, visual language, and left-right comprehension. Lesions can result in acalculia, apraxia, alexia, and Gerstmann syndrome.
Parietal Lobe Syndromes in Detail
- Hemineglect involves ignoring one side of the body or space.
- Topographical disorientation involves difficulty with navigation and spatial awareness.
- Conceptual Apraxia is an inability to use tools correctly or understand their function.
- Ideational Apraxia involves difficulty sequencing actions in the correct order.
- Ideomotor Apraxia involves difficulty performing actions even though they understand what to do.
- Speech Apraxia results in slow and effortful speech due to difficulties with articulating sounds.
- Bucco-facial Apraxia involves difficulty with facial movements, including non-speech related tasks like sucking and blowing.
- Alexia is an acquired inability to interpret written language.
- Acalculia is an inability to perform calculations, including an inability to read and understand numerical signs.
- Ishihara's color blindness test is a test for color perception.
- Visual field charting is a test of peripheral vision.
