Eurology at a general hospital and was suspected as possessing AD with parkinsonism. Dysarthria and dysphagia emerged at 34 and 35 years, respectively. Eleven years following the onset, she was admitted to the division of neurology at a university hospital. Neurological examination revealed limitation of upward and lateral gaze, bilaterally elevated tendon reflex in all four extremities, bilaterally good Babinski sign, spastic paraparesis, akinesia, and rigidity of your neck and 4 extremities. Parkinsonism was unresponsive to L-dopa therapy. She scored 20/30 points around the Mini-Mental State Examination , and around the WAIS-Revised, she obtained a verbal IQ score of 69, overall performance IQ score of 46, and full-scale IQ score of 54. Baseline blood and cerebrospinal fluid examinations have been regular. She could stroll without assistance until 37 years old. Brain MRI at 40 years demonstrated diffuse cerebral atrophy (Fig. 1a-d). At 42 years, she required tube feeding because of dysphagia. 99mTc-ECD single-photon emission computed tomography (SPECT) at 44 years disclosed hypoperfusion within the posterior part of the cingulate gyrus, precuneus, and parieto-occipital cortices (Fig. two).

Evident bilateral atrophy from the hippocampus and symmetric white matter atrophy with occipital predominance are noted. The width with the corpus callosum is decreased (c). The brain stem doesn’t show evident atrophy (d). e T1-weighted horizontal and f T2weighted horizontal pictures at 54 years. Diffuse cortical atrophy is progressed. The symmetric dilatation with the lateral ventricles becomes evident, suggesting the possible complication of idiopathic regular pressure hydrocephalus in addition to the atrophy with the white matterFig. two 99mTc-ECD SPECT images at age 44.

Serious diffuse atrophy such as the precentral gyrus (an asterisk) is noticed. b On a coronal section, serious atrophy is evident in the cortex and white matter with the frontal and temporal lobes. The basal ganglia also show extreme atrophy. The width of the corpus.
