Preclinical research is an essential aspect of biomedical science that aids in clarifying the pathophysiology of underlying illness and devising new treatments. This special issues brings together original research and review papers that pertain to the development of novel models and behavioral assays of symptoms of neuropsychiatric disorders, which may help to refine preclinical studies and to improve their translatability to the human condition.

Background: Alzheimer's disease (AD) agitation is a distressing neuropsychiatric symptom characterized by excessive motor activity, verbal aggression, or physical aggression. Agitation is one of the causes of caregiver distress, increased morbidity and mortality, and early institutionalization in patients with AD. Current medications used for the management of agitation have modest efficacy and have substantial side effects.

Background: The DL-3-n-butylphthalide (NBP), a multi-target neuroprotective drug, improving cognitive impairment in patient with vascular cognitive impairment has been confirmed. The efficacy of NBP in patients with cognitive impairment due to Alzheimer's disease (AD) remains unknown. This study aimed to evaluate the efficacy and safety of NBP in patients with mild cognitive impairment (MCI) due to AD though a clinical randomized controlled trail.

AXS-05 (45-mg dextromethorphan/105-mg bupropion), a novel, oral NMDA receptor antagonist and sigma-1 receptor agonist, approved by the FDA for major depressive disorder, is being investigated for treatment of AD agitation (ADA). AXS-05 has been evaluated in 2 randomized, double-blind studies: Phase 2 ADVANCE-1 (NCT03226522); Phase 3 ACCORD (NCT04797715).

Numerous drugs (including disease-modifying therapies, cognitive enhancers and neuropsychiatric treatments) are being developed for Alzheimer's and related dementias (ADRD). Emerging neuroimaging modalities, and genetic and other biomarkers potentially enhance diagnostic and prognostic accuracy. These advances need to be assessed in real-world studies (RWS).

Background: Agitation is a common and disabling symptom of Alzheimer's dementia (AD). Pharmacological treatments are recommended if agitation is not responsive to psychosocial intervention. Citalopram was effective in treating agitation in AD but was associated with cognitive and cardiac risks linked to its R- but not S-enantiomer.
