Syphilis is a multisystem chronic infection caused by treponema pallidum. It can cause psychiatric disorders including depression, mania, psychosis, personality changes, delirium and dementia. With the introduction of penicillin into practice, the number of cases with syphilis decreased and its incidence increased with AIDS and HIV seropositivity. In this article, we present a case of neurosyphilis that manifested itself with neuropsychiatric symptoms.

Syphilis is a generally sexually transmitted and multisystem disease caused by the spirochete Treponema pallidum. All of the organs of the body may be involved during the course of the disease. Neurosyphilis is a clinical form of syphilis with the central nervous system (CNS) involvement. While primarily meningeal and vascular structures are involved in early neurosyphilis, a parenchymal affection of the brain and spinal cord emerges at later stages of neurosyphilis. It presents with symptoms of meningitis, meningovasculitis and parenchymal neurosyphilis (presenting as tabes dorsalis and general paresis). Clinically, it can mimic a variety of psychiatric disorders such as depression, psychosis, mania, delirium, personality changes and dementia. During its progression making presentations similar to many systemic or neuropsychiatric diseases, syphilis is defined as "great imitator". Nowadays, neurosyphilis is a rare disease as a result of the widespread use of antibiotics that must be kept in mind in the differential diagnosis of neurological and psychiatric disorders. In this article, three neurosyphilis cases with different psychiatric presentations are reported and literature relevant to syphilis are reviewed.

Since E. Kraepelin isolated schizophrenia and bipolar disorder as heterogeneous diseases, attempts to categorize mental illnesses have continued to the DSM-5. Meanwhile, cases of psychosis occurring as a result of neurosyphilis have been reported. Whilst in some cases it is useful to divide mental illnesses, in others imposing such classifications may be not be feasible. Since 2008 numerous papers have been published showing that the same genes are related to an increased incidence of several psychiatric diseases including intellectual disorder, autism, ADHD, schizophrenia, bipolar disorder, and depression. This suggests that the theory that these are separate and heterogeneous diseases should be rejected. Aside from the categorical classification in the DSM, it is desirable to create new diagnostic criteria that capture mental illness as a spectrum.

Attempted and completed self-enucleation, or removal of one's own eyes, is a rare but devastating form of self-mutilation behavior. It is often associated with psychiatric disorders, particularly schizophrenia, substance induced psychosis, and bipolar disorder. We report a case of a patient with a history of bipolar disorder who gouged his eyes bilaterally as an attempt to self-enucleate himself. On presentation, the patient was manic with both psychotic features of hyperreligous delusions and command auditory hallucinations of God telling him to take his eyes out. On presentation, the patient had no light perception vision in both eyes and his exam displayed severe proptosis, extensive conjunctival lacerations, and visibly avulsed extraocular muscles on the right side. An emergency computed tomography scan of the orbits revealed small and irregular globes, air within the orbits, and intraocular hemorrhage. He was taken to the operating room for surgical repair of his injuries. Attempted and completed self-enucleation is most commonly associated with schizophrenia and substance induced psychosis, but can also present in patients with bipolar disorder. Other less commonly associated disorders include obsessive-compulsive disorder, depression, mental retardation, neurosyphilis, Lesch-Nyhan syndrome, and structural brain lesions.

Neurogranin (Ng) is a small protein usually expressed in granule-like structures in pyramidal cells of the hippocampus and cortex. However, its clinical value is not fully clear so far. Currently, Ng is proved to be involved in synaptic plasticity, synaptic regeneration, and long-term potentiation mediated by the calcium- and calmodulin-signaling pathways. Due to both the synaptic integrity and function as the growing concerns in the pathogenesis of a wide variety of neurological and mental diseases, a series of researches published focused on the associations between Ng and these kinds of diseases in the past decade. Therefore, in this review, we highlight several diseases, which include, but are not limited to, Alzheimer's disease, Parkinson disease, Creutzfeldt-Jakob disease, neuro-HIV, neurosyphilis, schizophrenia, depression, traumatic brain injury, and acute ischemic stroke, and summarize the associations between cerebrospinal fluid or blood-derived Ng with these diseases. We propose that Ng is a potential and promising biomarker to improve the diagnosis, prognosis, and severity evaluation of these diseases in the future.
