Background: Recent findings indicate that craving during alcohol withdrawal, also in abstinent patients, can relate to kindling phenomena caused by sensitization in temporo-limbic structures. Because limbic structures are involved in stress, anxiety, and emotional processing, kindling and temporolimbic seizure-like activity are also closely related to various psychiatric symptoms frequently presented without seizure disorders. Recent findings also show that these seizure-like processes are related to limbic irritability, which may also be significantly influenced by stressful life events.
Material/methods: The hypothesis tested in the present study is that limbic irritability could be closely related to craving symptoms. Therefore, limbic irritability and craving were assessed using psychometric measures in 40 alcohol-dependent patients and the results were compared with those of 40 healthy controls.
Results: Statistical analysis showed highly significant correlation (r=0.75, p<0.0000001) between limbic irritability (LSCL-33) and craving (ACQ-R) and highly increased limbic irritability scores in the patients compared with the healthy controls.
Conclusions: The results indicate that craving symptoms are related to the kindling process presented in the form of cognitive, affective, sensory, somatic, behavioral, and memory symptoms linked to limbic irritability and temporo-limbic seizure-like activity.

Objective: Here we investigated changes in topological properties of functional brain networks among individuals with Crohn's disease (CD) and to determine whether these changes are related to CD severity, as well as CD-associated anxiety and depression, which are regulated by the brain-gut axis mechanism.
Methods: In total, 31 individuals with CD, 21 with irritable bowel syndrome (IBS), and 20 healthy controls underwent functional magnetic resonance imaging. Individuals with CD or IBS were also evaluated using the Hospital Anxiety and Depression Scale-Anxiety (HADS-A) and Depression (HADS-D) scales, as well as the simple endoscopic score for CD (SES-CD).

A rare subtype of autoimmune encephalitis consists of antibodies targetting the alpha-amino-3-hydroxy-5- methyl-4-isoxazolepropionic acid receptor in the central nervous system. We describe the clinical presentation and autoimmune profile of the first case of alpha-amino-3- hydroxy-5-methyl-4-isoxazolepropionic acid receptor encephalitis with concurrent anti-acetylcholine receptor antibodies in Pakistan. The patient was a 58-year-old male who presented with the characteristic symptoms of limbic encephalitis with memory loss, irritability, agitation, and confusion.

Background: Considering the high comorbidity, shared risk factors, and genetic pathways between irritable bowel syndrome (IBS) and major depressive disorder (MDD), we hypothesized that there would be both shared and disorder-specific alterations in brain function.
Methods: A total of 39 IBS patients, 39 MDD patients, and 40 healthy controls (HCs) were enrolled and matched for sex, age, and educational level. All subjects underwent resting-state functional MRI.

Background: Neuropsychiatric symptoms (NPSs) are a distressful aspect of dementia and the knowledge of structural correlates of NPSs is limited. We aimed to identify associations of fronto-limbic circuit with specific NPSs in patients with various types of cognitive impairment.
Methods: Of 84 participants, 27 were diagnosed with mild cognitive impairment (MCI), 41 with Alzheimer's disease (AD) dementia and 16 with non-AD dementia.
Background: The central nervous system contains steroid receptors, particularly in the hypothalamic and limbic systems. These systems are responsible for driving certain emotions in humans, especially stress, anxiety, motivation, energy levels, and mood. Thus, corticosteroids may precipitate patients to experience these emotions.
