Background and Purpose: We aimed to investigate the rate of hospital admissions for cerebrovascular events and of revascularization treatments for acute ischemic stroke in Italy during the coronavirus disease 2019 (COVID-19) outbreak. Methods: The Italian Stroke Organization performed a multicenter study involving 93 Italian Stroke Units. We collected information on hospital admissions for cerebrovascular events from March 1 to March 31, 2020 (study period), and from March 1 to March 31, 2019 (control period). Results: Ischemic strokes decreased from 2399 in 2019 to 1810 in 2020, with a corresponding hospitalization rate ratio (RR) of 0.75 ([95% CI, 0.71–0.80] P <0.001); intracerebral hemorrhages decreased from 400 to 322 (hospitalization RR, 0.81 [95% CI, 0.69–0.93]; P =0.004), and transient ischemic attacks decreased from 322 to 196 (hospitalization RR, 0.61 [95% CI, 0.51–0.73]; P <0.001). Hospitalizations decreased in Northern, Central, and Southern Italy. Intravenous thrombolyses decreased from 531 (22.1%) in 2019 to 345 in 2020 (19.1%; RR, 0.86 [95% CI, 0.75–0.99]; P =0.032), while primary endovascular procedures increased in Northern Italy (RR, 1.61 [95% CI, 1.13–2.32]; P =0.008). We found no correlation ( P =0.517) between the hospitalization RRs for all strokes or transient ischemic attack and COVID-19 incidence in the different areas. Conclusions: Hospitalizations for stroke or transient ischemic attacks across Italy were reduced during the worst period of the COVID-19 outbreak. Intravenous thrombolytic treatments also decreased, while endovascular treatments remained unchanged and even increased in the area of maximum expression of the outbreak. Limited hospitalization of the less severe patients and delays in hospital admission, due to overcharge of the emergency system by COVID-19 patients, may explain these data.

Background: Intravenous (i.v.) thrombolysis with rt-PA within 3 h from symptom onset is the only approved treatment of pharmacological revascularization in acute ischemic stroke. However, little information exists on its use in elderly patients, in particular those aged >80 years, who at present are excluded from treatment. Methods: In a multicenter Italian study on i.v. thrombolysis, patients aged >80 years (n = 41) were compared with those aged ≤80 years (n = 207) regarding the percentage of symptomatic (nonfatal and fatal) intracerebral hemorrhage (SICH), favorable 3-month functional outcome (modified Rankin Scale score 0–2) and poor outcome (death or dependence, i.e. modified Rankin Scale score 3–5). Results: The percentage of SICH (nonfatal and fatal) was comparable between older (2.4%, 2.4%) and younger (2.4%, 2.4%) patient groups (p = 1.0). At 3 months, favorable outcome occurred in 44% and dependence in 22% of the older, and respectively in 58.5 and in 30.9% of the younger patients (p = 0.897). Patients aged >80 years had a higher mortality (34.1%) as compared to those aged ≤80 years (10.6%) (p < 0.001). Baseline National Institute of Health Stroke Scale score was the only statistically significant predictor of both mortality (OR = 1.26; 95% CI = 1.07–1.50) and poor outcome (OR = 1.39; 95% CI = 1.14–1.68) in the >80-year-old group. Conclusions: Acute ischemic stroke patients aged >80 years treated with i.v. rt-PA have a higher mortality than younger patients, but there are no differences for SICH nor for favorable outcome. Our data suggest that thrombolytic therapy should not be a priori denied for appropriately selected >80-year-old patients but randomized controlled clinical trials are necessary before definite recommendations can be given.

Forty-four patients suffering a stroke for the first time were examined within 10 h of the onset of symptoms; the tests performed on their admission to hospital, and thereafter on the third and seventh day, were 24-h Holter EKG with spectral analysis of heart rate variability, evaluation of arterial blood pressure and the levels of catecholamine in the blood and 24-h urine. The dynamic EKG on admission revealed that 31 (70.5%) out of the 44 patients already had arrhythmia. These alterations were observed in 9 (75%) out of 12 haemorrhagic patients with a significant (P < 0.05) prevalence compared to 22 (68.8%) of the 32 ischaemic ones. Arrhythmia showed up in 16 (76.2%) out of 21 cases with right hemisphere lesions and in 12 (63.2%) out of 19 cases of left hemisphere lesions; this difference was also significant (P<0.05). Arrhythmia was still present in 19 (43.2%) patients after 3 days and only in 2 (6.5%) patients after 7 days. The spectral analysis parameters on admission and after 3 days were significantly (P < 0.05) modified in patients with stroke plus arrhythmia, compared to patients with stroke alone and to control subjects, whereas no further differences were observed on the seventh day. Moreover, the percentage of patients with arterial hypertension and high levels of catecholamine greatly decreased from the third day onwards. A transient autonomic nervous system imbalance with prevalent sympathetic activity may justify this cardiovascular impairment during the hyperacute phase of stroke.

Cerebral microembolism is a very common event, especially during guidewire crossing and angioplasty alone compared with stenting. Further studies concerning the prognostic significance of this are advisable.

The heterogeneity of published data regarding post-stroke depression (PSD) prompted an Italian multicenter observational study (DESTRO), which took place in 2000-2003. The investigation involved 53 Italian neurology centers: of these, 50 treat acute patients and 3 provide rehabilitation care; 21 centres are in Northern Italy, 20 are in Central Italy, and 12 are in Southern Italy. The time schedule was articulated into three phases: registration of 6289 stroke patients; selection of 1817 cases and enrollment of 1074 patients; and follow-up for two years (1064 patients). Mood assessment was performed by evaluating depressive symptoms according to DSM IV and the Beck depression inventory (visual analog mood scale for aphasic patients). Depressed patients were also administered the Montgomery-Asberg depression rating scale. Scores were related to function (Barthel index, modified Rankin scale), cognition (MMSE), quality of life (SF-36), and clinical data. Data analysis will provide information on PSD prevalence, onset and evolution, correlation with ischemic clinical syndrome, impact on activities of daily living, cognitive level and quality of life. The few data available at the present time concern PSD prevalence in the first six months after stroke (33.6%). DESTRO is a longitudinal investigation of a large patient sample and is expected to provide insights into the relationship of PDS with the functional and clinical consequences of stroke.

Background: Transcranial Doppler monitoring shows a high prevalence of microemboli during carotid artery stenting (CAS); however, the occurrence of cerebrovascular symptoms (CVSs) does not seem to be related to the microembolic load. Objective: To evaluate embolic and hemodynamic transcranial Doppler monitoring findings and their relationships with the occurrence of procedural CVSs. Patients: Fifty-four patients who had carotid stenosis of more than 70% underwent a total of 57 CAS procedures during transcranial Doppler monitoring of mean blood flow velocity and microembolic signals in the middle cerebral artery. The occurrence of transient ischemic attack, transient monocular blindness, and stroke during the CAS procedure was considered CVSs. Results: Nine (15.8%) of the 57 patients had CVSs during the procedure (ie, 6 patients with transient ischemic attack, 1 with transient monocular blindness, 1 with a minor stroke, and 1 with a major stroke). The mean blood flow velocity median values were statistically significantly lower (PϽ.001) in the group of 9 patients with CVSs (36 cm/s; interquartile range, 32.3-38.5) compared with the 48 without CVSs (48 cm/s; interquartile range, 41.5-52). The median number of isolated microembolic signals was similar in the 2 groups (72; interquartile range, 66-81 vs 75; interquartile range, 67-83.5). The median number of microembolic signal showers (clusters of too many signals to be counted separately in one cardiac cycle) presented a nonsignificant prevalence in the patients with CVSs (9; interquartile range, 7.5-11.2) compared with the ones without CVSs (8.2; interquartile range, 7-9). Conclusion: The low flow velocity in the middle cerebral artery may impair the clearance of the microembolic load and should be considered a precursor of CVSs during the CAS procedure.

An actual estimate of the high prevalence of cerebrovascular disease in the elderly population, even in very old subjects, was thus achieved. Appropriate health care services consequently need to be planned.

Common postictal MRI findings include transient cortical T2 hyperintensity, restricted diffusion, and gyral and/or adjacent leptomeningeal contrast enhancement. In certain uncommon pathological conditions, other signal abnormalities can be present, suggesting a different underlying pathogenic mechanism. We report the case of a 66‐year‐old man, recently diagnosed with diabetes mellitus type 2, presenting with new‐onset visual and auditory hallucinations, “absence” seizures, and repeated peaks of hyperglycaemia without hyperketonaemia or increased serum osmolarity. EEG confirmed epileptic discharges in the right temporal region and MRI showed vast subcortical T2 hypointensity in the right temporal lobe, without any cortical hyperintensity, restricted diffusion, or contrast enhancement. Subcortical signal abnormality and EEG discharges resolved after a month of follow‐up, with a small juxtacortical gliotic focus as a sequela. Peaks in hyperglycaemia have been reported to be responsible for T2 hypointense subcortical abnormalities through a proconvulsant mechanism linked to increased ketone body concentrations. Hyperosmolarity and hyperketonaemia were not evident in this case, however, transient accumulation of free radicals that alter the intercellular space can be considered the presumable cause of this finding. In summary, it is important to consider any unusual findings on postictal MRI in order to avoid errors in interpretation.
