Article
Full-text available
Alzheimer’s disease (AD) is a neurodegenerative disorder with an increasing need for developing disease-modifying treatments as current therapies only provide marginal symptomatic relief. Recent evidence suggests the γ-aminobutyric acid (GABA) neurotransmitter system undergoes remodeling in AD, disrupting the excitatory/inhibitory (E/I) balance in...

Alzheimer’s disease (AD), the most common chronic neurodegenerative disorder, has complex neuropathology. The principal neuropathological hallmarks of the disease are the deposition of extracellular β-amyloid (Aβ) plaques and neurofibrillary tangles with neuroinflammation, a compromised blood-brain barrier (BBB) integrity, and neuronal synaptic dys...

Alzheimer's disease (AD) is the leading type of dementia worldwide. With an increasing burden of an aging population coupled with the lack of any foreseeable cure, AD warrants the current intense research effort on the toxic effects of an increased concentration of beta‐amyloid (Aβ) in the brain. Glutamate is the main excitatory brain neurotransmit...

Alzheimer's disease (AD) is a complex and chronic neurodegenerative disorder that involves a progressive and severe decline in cognition and memory. During the last few decades a considerable amount of research has been done in order to better understand tau-pathology, inflammatory activity and neuronal synapse loss in AD, all of them contributing...
Article
Full-text available
Glutamatergic and cholinergic dysfunction are well‐attested features of Alzheimer's disease (AD), progressing with other pathological indices of the disorder and exacerbating neuronal and network dysfunction. However, relatively little attention has been paid to the inhibitory component of the excitatory/inhibitory (E/I) network, particularly dysfu...
Article
Full-text available
Gamma‐aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system. GABA type A receptors (GABAARs) are severely affected in Alzheimer's disease (AD). However, the distribution and subunit composition of GABAARs in the AD brain are not well understood. This is the first comprehensive study to show brain region‐...

Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the vertebrate brain. In the past, there has been a major research drive focused on the dysfunction of the glutamatergic and cholinergic neurotransmitter systems in Alzheimer's disease (AD). However, there is now growing evidence in support of a GABAergic contribution to t...
