During attention tasks, the nicotinic antagonist, mecamylamine, impaired accuracy or reaction time (151, 152) and nicotinic agonists improved accuracy (153). PubMed:17009926
The hallmark psychotic symptoms of SZ are the positive cluster and include auditory hallucinations, delusional beliefs, and disorganized thoughts and speech. SZ patients also exhibit negative symptoms, including anhedonia, dysfunctional social interactions, and poverty of thoughts and speech, as well as cognitive disturbances affecting several behavioral domains, including working memory, attention, and executive function PubMed:24511233

By modulating activity-dependent events, nAChRs participate in fundamental aspects of synaptic plasticity that are involved in attention, learning, memory, and development (3, 12–16). PubMed:17009926
Experimental data using non-human primates and rodents have demonstrated that injuries introduced to basal forebrain cholinergic neurons that innervate the cortex lead to attention deficit PubMed:26813123
All these cholinergic alterations that take place in AD closely correlates with impaired attention and memory observed in patients PubMed:26813123
The cholinergic system is involved in critical physiological processes, such as attention, learning, memory, stress response, wakefulness and sleep, and sensory information PubMed:26813123
On the other hand, the facilitation of the cholinergic transmission by using the cholinesterase inhibitors can improve attention in humans PubMed:26813123
Disruption of cholinergic inputs to the cortex can impair attention and the use of instructive cues needed for decision-making related to ongoing behavior PubMed:26813123
Members of the mAChR family are widely expressed in various regions in the central nervous system (CNS) and in the peripheral system. They play crucial roles in diverse physiological processes such as memory, attention, nociception, motor control, sleep-wake cycles, and cardiovascular, renal, and gastrointestinal functions PubMed:24590577
Cotinine is a nicotine metabolite known for its positive effects on memory and attention and lower toxicity compared to nicotine (Hatsukami et al., 1997) PubMed:25514383
The cholinergic system is also involved in attention processes (Muir et al., 1993; Sarter and Bruno, 1997; Wenk, 1997) PubMed:25514383
In a mouse model, the lack of ACh receptors in the prefrontal cortex (PFC) was demonstrated to be responsible for attention deficit, restored by the expression of the receptor in this area (Guillem et al., 2011) PubMed:25514383
Null mutant beta2 mice were also tested to determine the role of this subunit in cognition. Guillem et al. (2011) showed that these mice exhibit an attention deficit which was restored by re-expression of this subunit with a lentiviral vector in the PFC PubMed:25514383
It improves sensory inhibition in schizophrenics and also moderately improves their neuropsychological deficits in attention (Olincy et al., 2006) PubMed:21482353
Acute administration of nicotine to AD patients has resulted in a measurable short-term improvement in learning, memory, and attentional performance (Jones et al 1992) PubMed:11230871
initially evaluated in normal subjects, GTS-21 was found to significantly improve attention and memory. in a second Phase i trial187, GTS-21 normalized P50 auditory gating in patients with schizophrenia. PubMed:19721446
(-)-Nicotine withdrawal symptoms might begin within a few hours after the last nicotine product, and include irritability/anger/stress/anxiety, sleep disturbances, depressed mood, craving, cognitive and attention deficits, and increased appetite. PubMed:28391535
