Psychiatric problems caused by brain tumors are quite infrequent.
Diagnosis is difficult because of the rare nature of this illness and the insidious nature of the disease process. The symptoms are unclear and the range of indicators point to several causes.
Having a clinical suspicion that mental symptoms are attributable to brain tumors is the first step in diagnosing them. When it comes to therapy and quality of life, early detection is essential.
An accurate diagnosis may be made with the help of a complete medical history and physical examination.
Neurologic indications, such as apraxia, visual field impairments, and anomia, provide subtle signals that may otherwise go unnoticed.
The first signs of the condition include personality shifts, sleep difficulties, and apathy, as well as weight loss and anorexia. Atypical symptoms, symptoms that are resistant to treatment, and the recurrence of previously controlled symptoms when other contributing factors (such as non-adherence to treatment, acute stressors, or medication changes) have been ruled out are other signs that point to the presence of brain tumors.
Can brain tumors cause mental illness?
Brain tumors are often detected using neuroimaging, which is the main method of detecting them. For anatomical evaluations, CT and MRI are employed. Metabolites in various parts of the brain may be measured using magnetic resonance spectroscopy.
Neuronal activity and local cerebral blood flow are studied using functional MRI (fMRI). Images are produced by radionuclides in positron emission tomography and single-photon emission computed tomography. In this essay, we’ll concentrate on the anatomical evaluations that doctors employ all the time.
Acute trauma and bleeding need the use of CT. Other benefits include better availability, fewer contraindications, and lower cost.. Necrosis, bleeding, cysts, tumors, and white-matter abnormalities may all be better seen with MRI because of its increased resolution. When it comes to spotting brain tumors and other soft-tissue abnormalities, MRI is preferred over computed tomography (CT).
For normal clinical settings, functional investigations seem to offer no significant benefits over CT and MRI, which are the most often utilized imaging modalities. Depending on subsequent modifications and clinical use, this might vary.
Depressive symptoms linked to a brain tumour
Doctors have released a case report in which they explain the diagnosis of a brain tumor in a lady with treatment-resistant depression. Brain tumors may only manifest as depressive symptoms. Patients with depression who have a normal neurological examination are unlikely to have a brain tumor, making the diagnosis more difficult.
They describe the instance of a 54-year-old lady who had been suffering from depression for six months. Suicidal thoughts and apathy were among the symptoms she was experiencing. She also had sleep disturbances and difficulty concentrating and paying attention.
There was no history of mental illness in her family, but she had lately experienced a number of stressful situations. Following a five-month trial, the antidepressant fluoxetine and the antianxiety drug bromazepam were found to have no effect and were subsequently stopped. She had numerous meningiomas, frequent tumors of the central nervous system, including a massive one in the left frontal lobe after brain CT and MRI scans.
These tumors, which affect the brain and spinal cord’s surrounding membranes, are not generally malignant. They may cause the skull to thin and erode. A portion of the left frontal lobe has been linked to depression in people with brain tumors, according to specialists. Patients with bigger meningiomas had a greater overall chance of developing mental health issues than those with smaller tumors.
Treatment-resistant depression, or apathy without dysphoric symptoms or with a diminished emotional response, the lack of neurological indicators, or instances with some anomalies in a neurological test, the team suggests brain imaging. New-onset psychosis, new mood or memory problems, new or unusual psychiatric symptoms, and personality changes may need brain imaging, according to specialists.
