  • Progress of resting-state network related to cognitive function in epileptic patients

    Nowadays, an increasing number of researches have shown that epilepsy, as a kind of neural network disease, not only affects the brain region of seizure onset, but also remote regions at which the brain network structures are damaged or dysfunctional. These changes are associated with abnormal network of epilepsy. Resting-state network is closely related to human cognitive function and plays an important role in cognitive process. Cognitive dysfunction, a common comorbidity of epilepsy, has adverse impacts on life quality of patients with epilepsy. The mechanism of cognitive dysfunction in epileptic patients is still incomprehensible, but the change of resting-state brain network may be associated with their cognitive impairment. In order to further understand the changes of resting-state network associated with the cognitive function and explore the brain network mechanism of the occurrence of cognitive dysfunction in patients with epilepsy, we review the related researches in recent years.

  • Comparative study of clinical features and vascular risk factors in patients with unexplained non-acute dizziness and headache in cerebrovascular disease clinic

    Objective To analyze the difference of clinical characteristics and vascular risk factors between patients with unexplained non-acute dizziness and headache, so that to bring new perspective on prevention of vascular risk factors and enhancement of symptoms among different patients. Methods The data of patients in the cerebrovascular disease clinic of the Department of Neurology, West China Hospital of Sichuan University between July 1th and September 30th, 2021 were collected retrospectively. The included patients were divided into dizziness group or headache group according to the complained. The clinical characteristics and risk factors of the two groups were compared. Results A total of 273 patients were included. There were 198 cases (72.5%) in dizziness group and 75 cases (27.5%) in headache group. Compared with headache group, patients in dizziness group were older, with a shorter course of disease, and accounted for a higher proportion of patients with symptoms related to body position, higher proportion of patients with hypertension and carotid plaque, and more vascular risk factors (P<0.05). Logistic regression results showed that patients with symptoms related to body position [odds ratio (OR)=7.025, 95% confidence interval (CI) (1.772, 28.488), P=0.007], at least one [OR=2.461, 95%CI (1.298, 4.664), P=0.006], two or more vascular risk factors [OR=2.314, 95%CI (1.033, 5.186), P=0.042] were independently associated with dizziness. The longer course of disease [OR=0.994, 95%CI (0.990, 0.997), P=0.001] was independently associated with headache. Conclusion Patients with non-acute unexplained dizziness and headache, especially those with dizziness, should pay more attention to the inquiry and treatment of vascular risk factors and psychopsychological factors.
