    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.
