​Can concussion affect speech?

​

Yes, concussions can affect smell and taste, particularly if the frontal or temporal lobes are involved. These senses rely on delicate nerve pathways that can be disrupted by sudden brain movement.

​

Loss of smell (anosmia) or altered taste may be temporary or, in some cases, long-lasting. Changes may be subtle, such as reduced sensitivity, or more noticeable, like complete loss.

​

Because smell plays an important role in safety and quality of life, persistent changes should be evaluated. Recovery may take weeks to months, depending on the extent of nerve disruption.
