Review
Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder widely recognized for its recurrent obsessions and compulsions, which may cause severe impairment worldwide. This review explores the difficulties in diagnosing OCD, its comorbidities, and its treatment approaches. Psychiatry and neuroscience face noteworthy obstacles in treating OCD, which is frequently misdiagnosed and inadequately addressed. This illness, which causes upsetting symptoms that interfere with day-to-day living, affects not only adults but also children and adolescents to a great extent. Despite the availability of multiple therapy methods, such as pharmacological and psychological approaches, many patients exhibit resistance, emphasizing the necessity for alternative therapies. OCD and other psychiatric conditions like bipolar disorder, schizophrenia, and attention deficit hyperactivity disorder substantially overlap, highlighting the complexity of mental health diagnoses. Furthermore, its comorbidity with these diseases further highlights OCD's intricacy. Several therapy considerations have been mentioned, such as using larger dosages of medications and combining different therapeutic approaches. Their association suggests possible common pathogenic pathways between OCD and other psychiatric illnesses. The review concludes that, given the significant number of people who still struggle with chronic symptoms, new treatment techniques and ongoing research are necessary, even in the face of improvements in the understanding and treatment of OCD.

Review
The field of stereotactic neurosurgery developed more than 70 years ago to address a therapy gap for patients with severe psychiatric disorders. In the decades since, it has matured tremendously, benefiting from advances in clinical and basic sciences. Deep brain stimulation (DBS) for severe, treatment-resistant psychiatric disorders is currently poised to transition from a stage of empiricism to one increasingly rooted in scientific discovery. Current drivers of this transition are advances in neuroimaging, but rapidly emerging ones are neurophysiological-as we understand more about the neural basis of these disorders, we will more successfully be able to use interventions such as invasive stimulation to restore dysfunctional circuits to health. Paralleling this transition is a steady increase in the consistency and quality of outcome data. Here, we focus on obsessive-compulsive disorder and depression, two topics that have received the most attention in terms of trial volume and scientific effort.

Review
Autism is a neurodevelopmental disorder characterized by deficits in social cognition and communication, restricted interests, and stereotyped behaviors. Frequently associated with sensory dysfunction, other neurodevelopmental disorders, neuropsychiatric disorders, epilepsy and/or sleep disorders. This condition will accompany people throughout their lives, which will generate various support and treatment needs. Although there are no drugs that modify the core symptoms of autism, various drugs have shown their usefulness in associated conditions. Atypical antipsychotics for hyperactivity, impulsivity, agitation, auto or heteroaggression crises. Serotonin reuptake inhibitors, to decrease anxiety, obsessive-compulsive symptoms, and irritability/agitation. Stimulants and atomoxetine used for hyperactivity, inattention, and impulsivity. Clonidine and guanfacine show some efficacy on hyperactivity and stereotyped behaviors. Buspirone has been used for restrictive behaviors and anxiety. There are drugs in the research phase such as oxytocin, vasopressin and even some developed for specific entities related to autism such as arbaclofen in Fragile X and Trofinetide that has just been approved for use in Rett syndrome. As specific entities and their pathophysiology are identified, it is likely that tailored treatments will be developed for each entity associated with autism..
