Twitching may be a reaction to SSRI drugs. If you take antidepressants or Cymbalta you may be have side effects called extrapyramidal signs from them.
You may get twitching from any stimulant, decongestants for nasal congestion, or even high caffeine intake. Stimulants for ADHD or recreational cocaine will cause twitching. Your own adrenalin levels may be elevated by fear, or being high strung and these can cause twitching.
Poor potassium levels and poor magnesium levels may cause twitching. Rapid changes in calcium levels also may affect the muscles. Elevated thyroid activity and disorders of the parathyroid glands will affect the muscles as well.
Low blood sugar spells. These are common in pre-diabetics. You may test out in a 2 hr glucose tolerance test as normal, but a 4 hr one will show the low spells.
There are DNA tests for MND:
