Transcript of The case of Janet

Hemineglect Malik Powell 10/15/12 Hemispatial neglect (Hemineglect) a neuropsychological condition in which, after damage to one hemisphere of the brain is sustained, a deficit in attention and awareness of one side of space is observed. Janet McKenzie Late afternoon on sunny Friday, Janet McKenzie ran her car into the left side of her garage door way. She had spent the day at work. Janet worked for an art supply company and seeing as how she herself was an amateur artist, she loved her work. However this Friday was not ordinary. It was Janet's birthday and her coworkers had given her a special brunch party. Janet had more festivities planned with her family later that night. When she found herself jolting to a stop at her doorway, Janet reasoned it was a lapse of attention due to all the excitement of her birthday. Something even stranger happened that night at her birthday party. When the time came for Janet to blow out the 50 candles on her birthday cake, Janet only blew out the candles on the right side. She seemed unaware of her bizarre behavior. When her husband pointed out the still burning candles, Janet remarked that they looked so pretty that she thought it'd be a shame to blow them out. Two days later, Janet's husband heard thumping sounds in the bathroom of their house. When he went to investigate, he found Janet laying on the floor, dazed and disoriented. By this time, I'm sure you're wondering what was wrong with Janet. Mini-Activity You guys are smart so, let me ask you, what do you think was wrong with Janet? What happened to her? 3B There are many different types of hemineglect but for the purposes of this presentation, I will focus on unilateral hemineglect manifestation
aetiology
case study: Janet
case study & suggested test We will look at: Manifestations Anton Räderscheidt Lovis Corinth Reynold Brown Aetiology Hemineglect can be caused by any kind of damage to the... Frontal lobe
Parietal lobe
Occipital lobe Many patients suffer from either tumors, strokes, lesions. Case study: Janet Janet had a right parietal tumor
Found to have marked visual and spacial neglect.
Left visual field cut
sensory loss in left arm How was this determined? Janet's tumor was discovered by CT scan. Janet was diagnosed with hemineglect after taking a few test. Treatment Steroids used to reduce swelling.
There was a surgery to "debulk" the mass
Janet then received radiation therapy
Janet received physical rehabilitation as well Post - treatment After janet's surgery, she returned to work . Janet worked part time for 18 months. sadly, her symptoms returned 23 months later. Janet's tumor had grown back and it was larger than before Janet refused any other surgeries and would only take her prescribed medication. Janet McKenzie passed 4 years after her diagnosis. Janet died due to server swelling of her brain. Due to the swelling, Janet's brain was not able to get oxygen through proper blood flow. Why Janet, WHY?? D: Why did janet die? Second case study: Mirror Agnosia Conducted by Vilayanur S. Ramachandran (Neuroscientist) Four patients
OS, BT, MR & JR
ages 63 to 87
All suffered from right parietal lesions
left field hemineglect confirmed in all Methodology A mirror was brought to each patients bedside and propped on their right side
The mirror used was selected to "obviously" resemble a mirror
Mirror was placed in the patients "good" field Stimuli another experimenter standing behind the patient
on cue would present a candy bar
positioned on the the visual left side of the patient
