Types of residual damage
Memory memory loss forgetfulness loss of train of thought inability to memorize instructions inability to complete a thought Spectrum of Attention difficulty concentrating easy distraction inability to focus when a competing stimulus coexists Reaction time slow reactions taking more time to think before answering Personality increased impulsivity reduction of inhibitions irritable, raising objections reduced […]
Recovery from coma
When the patient begins to wake up, the thought processes (cognitive functions) begin to become discernible and can be assessed. Patients usually wake up very gradually. Progress is made in slow steps that take time. Low-intensity controlled stimuli, such as speech, touch, sound, or visual stimuli, are more beneficial than longer stimuli, which […]
Secondary (metastatic) tumors
They are the most frequent brain tumors in adults (50%). About 10-15% of tumors metastasize in the brain. They can originate from the lung (44%), breast (10%), kidney (7%), gastrointestinal tract (6%), and melanoma (3%). The primary tumor is not found at a rate of 30%. The average survival of patients is 26-32 weeks, […]
Other brain tumors
Ependymomas Germinomas Neurocytoma Gangliogliomas Gliosarcomas Mixed malignant gliomas Oligodendrogliomas Lymphomas of the central nervous system Neuroectodermal tumors (myeloblastomas, neuroblastomas, esthesioneuroblastomas or olfactory neuroblastomas) Ependymomas Tumors of the epiphysis Colloid cysts Hemangioblastomas Chordomas Dermoid and epidermoid cysts
Malignant brain tumors
Astrocytomas (or gliomas) Astrocytomas are tumors that come from cells in the brain called astrocytes (due to their star shape). They are the most numerous cells in the brain, and their role is to support the nerve cells, to serve the nerve serves in terms of their energy, to facilitate their communication and they […]
Benign brain tumors
Acoustic Neuromas These are benign and slow-growing tumors that originate in the vestibular nerve, i.e. a part of the 8th cerebral nerve. They do not create metastases. They account for 6-8% of brain tumors. Tumor cells expand along the nerve, pressing on the rest of the brain nerves. They can even exert pressure on […]
