Alzheimer’s disease (AD) is the most common cause of dementia among the elderly. It is pathologically characterized by diffused extracellular deposits, senile plaques, and intracellular neurofibrillary tangles in the brain, responsible for neuronal dysfunction and cell death. Memory, language and other cognitive functions can be affected to a limited extent in the initial stage called mild cognitive impairment (MCI) or in Read More

Alzheimer’s disease is a neurodegenerative disorder leading to dementia. Scientific efforts in the last decade focused mainly on understanding pathophysiology of disease and possible pharmacological approach to alleviate cognitive decline symptoms. Amyloid cascade hypothesis though criticized, remains the leading hypothesis to understand pathogenic mechanisms of cognitive decline. Intriguingly, changes of metabolic Read More

The adrenergic system has an important role in normal central nervous system function as well as in brain disease. The locus coeruleus, the main source of norepinephrine in brain, is involved in the regulation of learning and memory, reinforcement of sleep-wake cycle and synaptic plasticity. In Alzheimer’s disease, locus coeruleus degeneration is observed early in the course of the disease, years before the onset of clinical co Read More

In the recent years, classical vascular risk factors have been suggested to play a role also in the development of degenerative dementia. Arterial hypertension has been implicated in the pathogenesis of dementia but no conclusive results have been produced yet; more recently, blood pressure variability (BPV) has been suggested as a more important risk factor for both silent brain vascular lesions and the development Read More

Epidemiological studies have suggested that obstructive sleep apnea syndrome (OSAS) may increase the risk of developing cognitive impairment. In patients with Alzheimer’s disease (AD), the prevalence of OSAS is much higher than that expected in cognitively healthy subjects. A deeper knowledge of the pathophysiological link between OSAS and AD and the demonstration that OSAS may directly influence the developme Read More

Inflammation is a common response of an individual against either exogenous or endogenous damage. The role of inflammation and of inflammatory cells recently emerged also in the pathogenesis of neurodegenerative disorders. Experimental evidences show how neurotransmitters, besides their role in the synapses, play a modulatory role during immune response. Drugs used for treatment of dem Read More

Hypertension is one of the most important modifiable risk factors of cardioand cerebrovascular diseases, responsible for the development of severe target organ damages. It has been shown that hypertension is associated with an increased prevalence of cognitive decline. It negatively affects the cognitive battery and accelerates dementia. Beside the known detrimental effects of senile hypertension on cognitive perfor Read More

Inflammation plays a pivotal role in the ischemia/reperfusion (I/R) injury. Inflammatory response is initiated by the detection of pathogen-associated molecular patterns and/or damage-associated molecular patterns via extracellular and intracellular pattern recognition receptors. The nucleotide-binding oligomerization domain–like receptor family, pyrin domain containing protein 3 (NLRP3) is a component of pattern recognition re Read More

Bipolar disorder (BD) affects 1 to 1.5% of the world population and consists of at least one manic episode (or hypomanic) associated with depressive episodes, interspersed with periods of euthymic mood. Recurrent crises lead to significant disability in BD patients, and correlates negatively to social and occupational adjustment. Such disability can be explained by a series of events, such as cortical and altered met Read More

The single feature of all malformations in cortical development is the clinical association with epilepsy. It has been proven that Sox-1 expression is essential during neurodevelopment and it is reported that Sox-1 knockout mice present spontaneous generalized seizures. Particularly in cerebellum, Sox-1 plays a key role in the Bergmann´s glia (BG) function, which allows the correct function of the Purkinje cells (PC). The Read More

Two thiosemicarbazide derivatives 1 and 2, three 2-amino-1,3,4-thiadiazole derivatives 3-5, and three N1- substituted-4-methyl-1,2,4-triazole-5-thione derivatives 6-8 were synthesized and evaluated for their central nervous system effects using rodent behavioral models. With the exception of 6, all compounds were devoid of neurotoxicity and they did not affect the body temperature of mice. New lead structures 1-4 with pot Read More

Baicalin (BA) and jasminoidin (JA) exert an additive effect in the treatment of cerebral ischemia, but the underlying molecular mechanism is still unclear. One hundred mice with focal cerebral ischemia/re-perfusion injury were divided into 5 groups: BA, JA, combination therapy (BJ), sham and vehicle. The differentially expressed genes identified by microarray consisting of 374 cDNAs were uploaded into GeneGo MetaCore softw Read More
