Acute-onset Mania in a Patient with Non-small Cell Lung Cancer.

Mania is a mood disorder characteristic of certain psychiatric conditions and is exhibited by high energy, elevated mood, irritability, insomnia, and pressured speech. Though commonly attributed to bipolar and schizoaffective disorders, mania may be precipitated by other non-psychiatric conditions, including substance abuse, medications, metabolic disturbance, and organic brain pathology. Steroid-induced mania is not uncommon and may present with a number of psychiatric symptoms.

Fatherhood contributes to increased hippocampal spine density and anxiety regulation in California mice.

Introduction: Parenting alters the hippocampus, an area of the brain that undergoes significant experience-induced plasticity and contributes to emotional regulation. While the relationship between maternal care and hippocampal neuroplasticity has been characterized, the extent to which fatherhood alters the structure and function of the hippocampus is far less understood.

Methods: Here, we investigated to what extent fatherhood altered anxiety regulation and dendritic morphology of the hippocampus using the highly paternal California mouse (Peromyscus californicus).
