A 73-year-old man was admitted with gait disturbance and dysarthria. He showed right-side cerebellar ataxia. Computed tomography of brain showed left thalamic bleeding. Nine months later, he was admitted again because of seizure and consciousness disturbance. He had a history of diabetes mellitus and gout for five years, but no hypertension. On physical examination the lungs and heart were normal. On neurological examination, he showed stupor,pupils and eye position were normal. He showed right hemiparesis and urinary incontinence. The deep tendon reflexes were (+) at the upper limbs and (2+) at the right knee and ankle. Blood pressure was 162/88 mmHg and glucose was 275 mg/dl. Other laboratory data were normal. Brain CT showed hemorrhage of the left frontal lobe. The cystatin C level in cerebrospinal fluid was 68 ng/ml. Therefore we suspected cystatin C deposit amyloid angiopathy. In this case, thalamic hemorrhage was initially thought to be amyloid angiopathy. In cases of cerebral hemorrhage in the elderly without hypertension, we must be considered amyloid angiopathy.

We observed two families with a dominantly inherited complex neurological syndrome with onset in adulthood. Family F included 9 affected in four generations. One patient showed prominent anticipation of onset age. Onset was with cerebellar signs followed by dementia, psychiatric symptoms, seizures, and extrapyramidal features. Family M included 14 affected individuals in five generations. Presenting symptoms were either psychiatric and cognitive impairment or a cerebellar syndrome. Extrapyramidal features, dysphagia, incontinence, seizures, and myoclonus may occur. In both families magnetic resonance imaging showed marked atrophy of the brain and cerebellum. Molecular analyses demonstrated an expanded CAG/CAA repeat in the in the TATA box-binding protein (TBP) gene (SCA17).

Accurate renal function measurement is important for identification of chronic renal disease which may allow early implementation of renoprotective therapy and proper medication dosing among elderly individuals. This paper proposed to review available data about the strengths and weaknesses of current methods of measuring and estimating of renal function and to appoint which of them is the best in older people. Serum creatinine and creatinine clearance are inaccurate screening tests for renal failure in elderly subjects leading to under-recognition and/or underestimation of the degree of renal failure due to the reduced muscle mass and the inappropriate collection of a timed urine sample (urinary incontinence, cognitive impairment). For all their limitations, formulaic estimates of glomerular filtration rate can provide better information in this population. Further researches must be focused on development of a more precise estimation equation and on implementation in clinical practice of a novel marker of renal function, serum cystatin C, claimed to be superior to plasma creatinine in the elderly individuals.
