The area of a triangle is half the base times the height. The âbaseâ of the triangle is any side you choose to make the base. The height is then the distance measured at right angles from the base to the apex, the furthermost point of the triangle not on the base.
Late/chronic Lyme neuroborreliosis is characterized by various neuropsychiatric manifestations [48, 80, 81]. The clinical symptoms include, seizures, chorea, dysphasia, ataxia, chronic spastic para- tetra- and hemiparesis [72, 76, 82-88] sometimes recurrent [89].
Bone and joint symptoms include arthralgias, low back pain, spine and joint pain, and, rarely, joint swelling. These symptoms affect as many as 55-80% of patients. Neuropsychiatric symptoms of brucellosis are common despite the rare involvement of the nervous system. Headache, depression, and fatigue are the most frequently reported neuropsychiatric symptoms. Gastrointestinal symptoms, present in 50% of patients, include abdominal pain, constipation, diarrhea, and vomiting. Neurologic symptoms of brucellosis can include weakness, dizziness, unsteadiness of gait, and urinary retention. Symptoms associated with cranial nerve dysfunction may affect persons with chronic CNS involvement.
