Lesion locations causing parkinsonism were functionally connected to a common network of regions including the midbrain, basal ganglia, cingulate cortex, and cerebellum. The most sensitive and specific connectivity was to the claustrum.
What clinical manifestations are most commonly present in a patient diagnosed with Parkinson's disease?
As in Parkinson’s, many common symptoms may develop, including tremor; muscle rigidity or stiffness of the limbs; gradual loss of spontaneous movement, often leading to decreased mental skill or reaction time, voice changes, or decreased facial expression; gradual loss of automatic movement, often leading to decreased …

The collarbone, or clavicle, is one of the most frequently broken bones. It’s the most common type of fracture in children and teens. Seniors usually break their collarbones from a hard fall. Younger adults, teens, and children are more likely to break their collarbone in a car accident or from playing sports.

A transverse fracture occurs when a bone breaks at a 90-degree angle to the long axis of the bone. This typically occurs when a blow transmits a large amount of force directly perpendicular to the bone. Transverse fractures require an orthopedic trauma surgeon. Oblique fracture.

(meh-TAS-tuh-size) To spread from one part of the body to another. When cancer cells metastasize and form secondary tumors, the cells in the metastatic tumor are like those in the original (primary) tumor.
What causes osteoblastic?
Other damage can result when new bone is formed due to chemicals released by the tumor. This new bone may be weak and deformed. When this occurs, it’s known as osteoblastic, or bone formation, damage. This occurs in cancers that begin as prostate, bladder, or stomach cells.
What cancers cause blastic bone lesions?
Prostate cancer has a unique predilection for metastasis to bone, which most commonly presents as blastic or sclerotic bone lesions, resulting in abnormal growth and stimulation of bone mineralization [3].
