Study Notes

Case Studies in Neuropsychology

Case 1 involves a patient referred with memory and attention impairments, loss of emotional control, and repetition of actions. Frontal lobe lesions are evident on MRI.
Possible diagnosis: Dysexecutive syndrome or frontal lobe syndrome. Frontal lobe damage disrupts planning, decision-making, emotional regulation, and working memory.
Frontal lobe functions: crucial for executive functions, problem-solving, emotional regulation, production (Broca's area), language, and social behaviors. Damage leads to behavioral problems, difficulty concentrating, and personality changes. Significant impact on daily life.
Cognitive symptoms: memory, planning & reasoning impairments, attention deficits, difficulty with consequences, and confabulation (false memories).
Emotional symptoms: loss of inhibition, emotional control, and poor impulse control.
Behavioral symptoms: inappropriate use of objects, repetition of actions.
Neuroimaging techniques: MRI is helpful. Potential additional techniques include fMRI, DTI, and PET scans. These tools assess different aspects of brain function.

Case 2

About a 65-year-old patient, with disinhibition, impulsivity and some mild speech impairment. Some memory problems are also noted. Neuroimaging shows large frontal and mild temporal impairment. Genetic testing reveals Tau protein accumulation.
Possible diagnosis: Frontotemporal Dementia (FTD).
Frontal and temporal lobes: govern cognitive and emotional functions, decision-making, problem-solving, emotional regulation, language, and memory.
Tau protein accumulation: damages brain cells, impacting personality changes, impaired judgment, loss of empathy, and disinhibition, and often leading to language difficulties.

Case 3

A patient with a history of chronic alcoholism presents with symptoms of amnesia, confabulation (fabricating memories), apathy, and lack of insight. A CT scan reveals neuronal loss and gliosis in the periventricular gray matter.
Possible diagnosis: Korsakoff syndrome (KS) resulting from Thiamine deficiency, causing damage to the mammillary bodies and thalamus.
Neuroimaging techniques: MRI (detects atrophy of mammillary bodies and thalamus), DTI (assesses damage to white matter tracts in memory circuit), and FDG-PET (identifies hypometabolism in diencephalic regions).

Case 4

A 75-year-old male patient experiences a sudden, short period of amnesia (4 hours), accompanied by headache and nausea.
Possible diagnosis: Transient Global Amnesia (TGA).
Core features: acute onset of anterograde amnesia (inability to form new memories) with intact self-awareness, repetitive questioning, and difficulty forming new memories.
Neuroimaging techniques include CT scan (to rule out vascular issues like stroke, TIA) and MRI with DWI (Diffusion-weighted Imaging; to detect possible focal areas of injury).
Emotional impact: counselling to manage anxiety and recurrence.

Case 5

A 72-year-old patient with memory loss, signs of agitation, anomia (word-finding difficulties), and hippocampal atrophy.
Possible diagnosis: Alzheimer's Disease (AD).
Symptoms: Memory and language difficulties, and memory deficits.
Neuroimaging techniques: FDG-PET (examines glucose metabolism), Amyloid PET (detects amyloid-β plaques), and tau PET (detects tau tangles).
Assessment: tests for episodic memory and naming deficits

Case 6

A patient presents with speech comprehension impairment (while repetition remains intact), mild meaning disturbances of words, and lesions in the white matter tracts in the temporal lobe.
Possible diagnosis: Transcortical Sensory Aphasia (TSA)
Symptoms: difficulty understanding speech, but the ability to repeat words and sentences, and the presence of word meaning disturbances.

Case 7

A patient experiencing fluent speech with comprehension deficits following a TBI (traumatic brain injury).
Possible Diagnosis: Wernicke's Aphasia.
Symptoms: difficulties with word selection, repetition, and disturbances in sentence meaning.
Key features: fluent but meaningless speech, impaired comprehension, intact repetition.

Case 8

A 28-year-old patient exhibits a lack of repetition and word-finding difficulty.
Possible Diagnosis: Conduction Aphasia
Symptoms: Impaired repetition and mild naming and writing deficits.
Patient is aware of these errors, but their speech may still lack accuracy.

Case 9

A patient with telegraphic speech, lack of prosody, impaired repetition and naming, agrammatism, motor difficulties, like dysarthria, right hemiparesis, and ideomotor apraxia.
Possible Diagnosis: Broca's Aphasia
Symptoms: non-fluent and effortful speech; intact ability for repetition and comprehension
Neuroimaging: MRI or fMRI to assess areas linked to language production and/or speech.

Case 10

A patient with memory impairments, disinhibition, apathy, loss of empathy, impulsivity, and inappropriate social behaviors.
Possible Diagnosis: Frontotemporal Dementia (FTD)
Symptoms: severe impairment in frontal and temporal lobes.
Neuroimaging: MRI, FDg-PET to see frontal and temporal atrophy.
