Like clumsiness, loosing feeling in a part of your body or face is something to keep an eye on. Particularly if a tumor forms on the brain stem—the place where your brain connects with your spinal cord—you may experience loss of feeling or clumsy movements.
Regardless of your type of tumor, seizures are often one of the first signs of trouble. Irritation from the tumor makes the [brain’s] neurons fire uncontrollably, and you get abnormal movements. Like tumors, seizures take many forms. You could experience whole-body convulsions, or jerking or flexing confined to one limb or one part of your face.
If you find yourself fumbling with keys, missing steps, or struggling with your balance, that sort of clumsiness in your arms, legs, or hands could be a sign of trouble. Problems speaking, swallowing, or controlling your facial expressions are some of the ways clumsiness could show up in or around your head, he adds.
While it’s true that tumors can cause big shifts in a person’s behavior or personality, the types of radical transformations you sometimes hear about—or see in movies—are uncommon. People with tumors are more likely to have issues remembering things, to feel confused, or to suffer less-dramatic thinking problems, he says.
Blurry vision, double vision, and loss of vision are all associated with tumors. You may also see floating spots or shapes—or what’s known as an aura.
